• • Saving Configuration Changes, page 1-11 For an overview of the Catalyst 4500 series switch Cisco IOS configuration, refer to the Catalyst 4500 Series Switch Cisco IOS Software Configuration Guide. Getting Help To display a list of commands that you can use within a command mode, enter a question mark (?) at the system prompt.
To display keywords for a command, enter a question mark (?) at the command prompt or after entering part of a command followed by a space. The Catalyst 4500 series switch software displays a list of available keywords along with a brief description of the keywords. For example, if you are in global configuration mode and want to see all the keywords for the arap command, you enter arap ?.
Because a is not displayed, it <cr> indicates that you must enter more information to complete the command. Catalyst 4500 Series Switch Cisco IOS Command Reference—Release IOS XE 3.4.0SG and IOS 15.1(2)SG) OL-27596 -01...

Return to complete the command. In this example, press Return to Switch(config-if)# channel-group 1 mode auto Switch(config-if)# complete the command. Catalyst 4500 Series Switch Cisco IOS Command Reference—Release IOS XE 3.4.0SG and IOS 15.1(2)SG) OL-27596 -01...
(?) at the system prompt. When you start a session on the Catalyst 4500 series switch, you begin in user mode, often called EXEC mode. Only a limited subset of the commands are available in EXEC mode. In order to have access to all commands, you must enter privileged EXEC mode.
Examples of simple regular expressions are Serial, misses, and 138. Examples of complex regular expressions are 00210..., ( is ), and [Oo]utput. Catalyst 4500 Series Switch Cisco IOS Command Reference—Release IOS XE 3.4.0SG and IOS 15.1(2)SG) OL-27596 -01...

Support for this command was introduced on the Catalyst 4500 series switch. Usage Guidelines With Cisco Release 12.2(25) EWA, you can use the dot1x guest-vlan supplicant command to place an 802.1X-capable host into a guest VLAN. Prior to Cisco Release 12.2(25)EWA, you could only place non-802.1X capable hosts into a guest VLAN.
Use the multi-domain keyword to enable MDA on a port. MDA divides the port into both a data domain and a voice domain. MDA allows both a data device and a voice device, such as an IP phone (Cisco or non-Cisco), on the same IEEE 802.1x-enabled port.

When the switch detects a new device on a port it applies the appropriate ASP macro. When a link-down event occurs on a port, the switch removes the macro. For example, when you connect a Cisco IP phone to a port, ASP automatically applies the IP phone macro. The IP phone macro enables quality of service (QoS), security features, and a dedicated voice VLAN to ensure proper treatment of delay-sensitive voice traffic.

This command was introduced on the Catalyst 4500 series switch. Usage Guidelines Before attempting an ISSU, you should know the compatibility level between the old and the new Cisco IOS software versions on the active and the standby supervisor engines. ISSU will not work if the two versions are incompatible.
Page 850
Cisco IOS images, the two versions of the Cisco IOS images are declared “Incompatible”. This means that an in-service upgrade or downgrade between these versions is not possible. The systems operates in RPR mode during the period when the versions of Cisco IOS at the active and standby supervisor engines differ.

Session is bidirectional and a reliable connection is established between two endpoints. Sync-data and negotiation messages are sent to the peer endpoint through a session. On a Catalyst 4500 series switch, each ISSU-aware client has a maximum of one session at each endpoint.
This command was introduced on the Catalyst 4500 series switch. Usage Guidelines It might take several seconds after the issu loadversion command is entered for Cisco IOS software to load onto the standby supervisor engine and the standby supervisor engine to transition to SSO mode. If you enter the show issu state command too soon, you might not see the information you need.
