Management Vlans; Changing The Management Vlan For A New Switch - Cisco Catalyst 2950 Software Manual

Chapter 8 Configuring VLANs
The Catalyst 2950 switches do not support ISL trunking.
Note
Trunking is not supported on all switches. For the list of products that support trunking, refer to the
release notes.

Management VLANs

Communication with the switch management interfaces is through the switch IP address. The IP address
is associated with the management VLAN, which by default is VLAN 1.
The management VLAN has these characteristics:
•
•
•
•
Before changing the management VLAN on your switch network, make sure you follow these
guidelines:

If you are using SNMP or CMS to manage the switch, ensure that the port through which you are
connected to a switch is in the management VLAN.
For information about the role management VLANs play in switch clusters, see the

Changing the Management VLAN for a New Switch

If you add a new switch to an existing cluster and the cluster is using a management VLAN other than
the default VLAN 1, the command switch automatically senses that the new switch has a different
management VLAN and has not been configured. The command switch issues commands to change the
management VLAN on the new switch to match the used by the cluster. This automatic change occurs
for new, out-of-box switches that do not have a config.text file and for which there have been no changes
to the running configuration.

It is created from CMS or through the CLI on static-access and dynamic-access and trunk ports. You
cannot create or remove the management VLAN through Simple Network Management Protocol
(SNMP).
Only one management VLAN can be administratively active at a time.
With the exception of VLAN 1, the management VLAN can be deleted.
When created, the management VLAN is administratively down.
The new management VLAN should not have an Hot Standby Router Protocol (HSRP) standby
group configured on it.
You must be able to move your network management station to a switch port assigned to the same
VLAN as the new management VLAN.
Connectivity through the network must exist from the network management station to all switches
involved in the management VLAN change.
Switches running a IOS software version that is earlier than Cisco IOS 12.0(5)XP cannot have the
management VLAN changed.
Switches running Cisco IOS 12.0(5)XP should be upgraded to the current software release as
described in the release notes.
