Page 56: Overview
Using the Command Line Interface (CLI) Overview Overview The CLI is a text-based command interface for configuring and monitoring the switch. The CLI gives you access to the switch’s full set of commands while providing the same password protection that is used in the web browser interface and the menu interface.
Page 57: Privilege Levels At Logon
Using the Command Line Interface (CLI) Using the CLI When you use the CLI to make a configuration change, the switch writes the change to the Running-Config file in volatile memory. This allows you to test your configuration changes before making them permanent. To make changes permanent, you must use the write memory command to save them to the Startup-Config file in non-volatile memory.
Page 58: Privilege Level Operation
Using the CLI C a u t i o n HP strongly recommends that you configure a Manager password. If a Man ager password is not configured, then the Manager level is not password- protected, and anyone having in-band or out-of-band access to the switch may be able to reach the Manager level and compromise switch and network security.
Page 59: Manager Privileges
Using the Command Line Interface (CLI) Using the CLI Manager Privileges Manager privileges give you three additional levels of access: Manager, Global Configuration, and Context Configuration.

Page 67: Configuration Commands And The Context Configuration Modes
Using the Command Line Interface (CLI) Using the CLI Configuration Commands and the Context Configuration Modes You can execute any configuration command in the global configuration mode or in selected context modes. However, using a context mode enables you to execute context-specific commands faster, with shorter command strings.
Page 68 Using the Command Line Interface (CLI) Using the CLI In the port context, the first block of commands in the “?” listing show the context-specific commands that will affect only ports C3-C6. The remaining commands in the listing are Manager, Operator, and context commands.
Page 69 Using the Command Line Interface (CLI) Using the CLI VLAN Context . Includes VLAN-specific commands that apply only to the selected VLAN, plus Manager and Operator commands. The prompt for this mode includes the VLAN ID of the selected VLAN. For example, if you had already configured a VLAN with an ID of 100 in the switch: HPswitch(config)# vlan 100 Command executed at configuration level to enter VLAN 100 context.

Page 150: Just Want A Quick Start With Ip Addressing?
If you just want to give the switch an IP address so that it can communicate on your network, or if you are not using VLANs, HP recommends that you use the Switch Setup screen to quickly configure IP addressing. To do so, do one of the following: Enter setup at the CLI Manager level prompt.

Page 159: Dhcp/Bootp Operation
Configuring IP Addressing IP Configuration DHCP/Bootp Operation Overview. DHCP/Bootp is used to provide configuration data from a DHCP or Bootp server to the switch. This data can be the IP address, subnet mask, default gateway, Timep Server address, and TFTP server address. If a TFTP server address is provided, this allows the switch to TFTP a previously saved configuration file from the TFTP server to the switch.
Page 160 Configuring IP Addressing IP Configuration DHCP Operation. A significant difference between a DHCP configuration and a Bootp configuration is that an IP address assignment from a DHCP server is automatic. Depending on how the DHCP server is configured, the switch may receive an IP address that is temporarily leased. Periodically the switch may be required to renew its lease of the IP configuration.

Page 247 Port Trunking Overview Port Connections and Configuration: All port trunk links must be point- to-point connections between a switch covered by this guide and another switch, router, server, or workstation configured for port trunking. No inter vening, non-trunking devices are allowed. It is important to note that ports on both ends of a port trunk group must have the same mode (speed and duplex) and flow control settings.
Page 248: Port Trunk Features And Operation
LACP requires full-duplex (FDx) links of the same media type (10/100Base-T, 100FX, etc.) and the same speed, and enforces speed and duplex conformance across a trunk group. For most installations, HP recommends that you leave the port Mode settings at Auto (the default). LACP also operates with Auto-10, Auto-100, and Auto-1000 (if negotiation selects FDx), and 10FDx, 100FDx, and 1000FDx settings.
Page 249: Trunk Configuration Methods
Port Trunking Trunk Configuration Methods Trunk Configuration Methods Dynamic LACP Trunk: The switch automatically negotiates trunked links between LACP-configured ports on separate devices, and offers one dynamic trunk option: LACP. To configure the switch to initiate a dynamic LACP trunk with another device, use the interface command in the CLI to set the default LACP option to Active on the ports you want to use for the trunk.

Page 251 Port Configuration: The default port configuration is Auto, which enables a port to sense speed and negotiate duplex with an Auto-Enabled port on another device. HP recommends that you use the Auto setting for all ports you plan to use for trunking.
Page 252 Port Trunking Trunk Configuration Methods Spanning Tree: 802.1D (STP) and 802.1w (RSTP) Spanning Tree operate as a global setting on the switch (with one instance of Spanning Tree per switch). 802.1s (MSTP) Spanning Tree operates on a per-instance basis (with multiple instances allowed per switch).

Port Trunking Menu: Viewing and Configuring a Static Trunk Group Menu: Viewing and Configuring a Static Trunk Group Important Configure port trunking before you connect the trunked links to another switch, routing switch, or server. Otherwise, a broadcast storm could occur. (If you need to connect the ports before configuring them for trunking, you can temporarily disable the ports until the trunk is configured.
Page 254 Port Trunking Menu: Viewing and Configuring a Static Trunk Group • For proper trunk operation, all ports in a trunk must have the same media type and mode (such as 10/100TX set to 100FDx, or 100FX set to 100FDx). The flow control settings must also be the same for all ports in a given trunk.
Page 255: Cli: Viewing And Configuring Port Trunk Groups

If the Spanning Tree Protocol is enabled, the delay may be up to 30 seconds. 8. Connect the trunked ports on the switch to the corresponding ports on the opposite device.
Page 256 Port Trunking CLI: Viewing and Configuring Port Trunk Groups Using a port list specifies, for switch ports in a static trunk group, only the ports you want to view. In this case, the command specifies ports A5 through A7. However, because port A6 is not in a static trunk group, it does not appear in the resulting listing: Port A5 appears with an example of a name that you can optionally assign using the Friendly Port Names feature.

This effectively sets an inbound usage level on a given port, and is a tool for enforcing maximum service level commitments granted to network users.
Page 276: Configuring Inbound Rate-Limiting
– Configuring a rate limit of 0 (zero) on a port blocks all inbound traffic on that port. However, if this is the de- sired behavior for the port, HP recommends that you use < port-list > disable to disable the port instead of configuring a rate limit of 0.

Port Traffic Controls Rate-Limiting The outbound port priority queues 1 - 4 for ports A1-A2 are configured with the indicated Guaranteed Minimum Bandwidth percentages. Ports A3-A5 are configured with a rate limit of 60 %. (Ports A1 and A2 are not configured for rate-limiting.) Figure 13-2.
Page 279 Port Traffic Controls Rate-Limiting rate limit. In this case, the inbound traffic flow does not reach the configured rate and lower priority traffic is not forwarded into the switch fabric from the rate-limited port. (This behavior is termed “head-of-line blocking” and is a well-known problem with flow-control.) In another type of situation, an outbound port can become oversubscribed by traffic received from multiple rate-limited ports.
Page 280 Port Traffic Controls Rate-Limiting Network Stress Conditions: Under normal network operating condi ■ tions, rate-limiting limits inbound traffic on a port to no more than the configured level. However, under network stress conditions, the port may allow occasional bursts of inbound traffic forwarding that exceed the configured rate.

Page 323: General Lldp Operation
Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) General LLDP Operation An LLDP packet contains data about the transmitting switch and port. The switch advertises itself to adjacent (neighbor) devices by transmitting LLDP data packets out all ports on which outbound LLDP is enabled, and reading LLDP advertisements from neighbor devices on ports that are inbound LLDP- enabled.
Page 324: Lldp Configuration Options
Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) LLDP Configuration Options Enable or Disable LLDP on the Switch. In the default configuration, LLDP is globally enabled on the switch. To prevent transmission or receipt of LLDP traffic, you can disable LLDP operation (page 14-37) Change the Frequency of LLDP Packet Transmission to Neighbor Devices.

Page 327: Lldp Operating Rules
Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) LLDP Operating Rules Port Trunking. LLDP manages trunked ports individually. That is, trunked ports are configured individually for LLDP operation, in the same manner as non-trunked ports. Also, LLDP sends separate advertisements on each port in a trunk, and not on a per-trunk basis.
Page 328: Cl Switches
Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) LLDP and CDP Data Management on the Series 3400cl and 6400cl Switches This section applies only to the Series 3400cl and 6400cl switches. LLDP (Link-Layer Discovery Protocol) operation on the 3400cl and 6400cl switches includes transmitting LLDP packets to neighbor devices and reading LLDP packets received from neighbor devices.
Page 329 Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) N o t e Because the Series 3400cl and Series 6400cl switches do not generate CDP packets, these switches do not appear in the CDP data collected by any neighbor devices running CDP. A Series 3400cl or 6400cl switch with CDP disabled forwards the CDP packets it receives from other devices, but does not store the CDP information from these packets in its own MIB.
Page 330: Switches
Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) Disabling CDP Data Collection on 3400cl and 6400cl Switches Disabling CDP means that the switch forwards all inbound CDP packets it receives from neighbor devices, but does not store CDP neighbor information from these devices.
Page 331: Viewing The Current Lldp Configuration
Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) In the default configuration, LLDP is enabled and in both transmit and receive mode on all active ports. The LLDP configuration includes global settings that apply to all active ports on the switch, and per-port settings that affect only the operation of the specified ports.
Page 332 Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) For example, show lldp config produces the following display when the switch is in the default LLDP configuration: Note: This value corresponds to the lldp refresh-interval command (page 14-38).

Page 335 Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) Changing the Delay Interval Between Advertisements Generated by Value or Status Changes to the LLDP MIB. The switch uses a delay- interval setting to delay transmitting successive advertisements resulting from these LLDP MIB changes. If a switch is subject to frequent changes to its LLDP MIB, lengthening this interval can reduce the frequency of successive advertisements.
Page 336: Configuring Snmp Notification Support
Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) Changing the Reinitialization Delay Interval. In the default configura tion, a port receiving a disable command followed immediately by a txonly, rxonly, or tx_rx command delays reinitializing for two seconds, during which time LLDP operation remains disabled.

Page 348 Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) LLDP Packet Forwarding: If CDP is globally disabled on a switch, the switch forwards CDP packets received from a neighbor CDP device instead of reading and dropping them. However, an 802.1D-compliant switch does not forward LLDP packets, regardless of whether LLDP is globally enabled or disabled on the switch.
Page 349: Cdp On The Series 5300Xl Switches
To take advantage of CDP in Series 5300xl switches, you should have a working knowledge of SNMP operation and an SNMP utility capable of polling the switches for CDP data. HP’s implementation of CDP places specific data into the switch’s Management Information Base (MIB). However, retrieval of these data for network mapping is dependent on the operation of your SNMP utility.
