Cluster Management and Membership

When the Catalyst 1900 switch joins a cluster, the following conﬁguration settings change:

• The highest privileged-level password (encrypted or unencrypted) of the command

switch becomes the password to the Catalyst 1900 Switch Manager, management

console, and CLI. If the command switch does not have a password, then no password

is required when accessing the Catalyst 1900 switch from the command switch. (See the

“Changing the Switch Password” section on page 3-8 or the “Console Settings Menu”

section on page 4-6.)

• The host name you assign to the Catalyst 1900 switch is kept even when the switch joins

or leaves a cluster. If the Catalyst 1900 switch does not have a name when it joins a

cluster, the command switch assigns it a name. (See the “Switch Host Name” section on

page 3-6 and the “System Conﬁguration Menu” section on page 4-11.)

• The command switch propagates its ﬁrst SNMP Read and Write community strings as

the last Read and Write community strings for the member switch. If the joining

Catalyst 1900 switch already has four Read and four Write community strings, the

command switch overrides the fourth community strings with its own ﬁrst community

strings. When the switch leaves the cluster, the command-switch community strings are

deleted.

Each string from the command switch contains up to 27 characters and a sufﬁx

“@esNN” where NN is the member switch number. (See the “Changing the SNMP

Settings” section on page 3-35 or the “Network Management (SNMP) Conﬁguration

Menu” section on page 4-24.)

Caution Do not use “@es” in the community strings you deﬁne for the switch. When the

switch joins a cluster, any community string containing “@es” is deleted.

For complete information about cluster management and membership, refer to the

Cisco IOS Desktop Switch Software Conﬁguration Guide, Catalyst 2900 Series XL and

Catalyst 3500 Series XL Cisco IOS Release 12.0(5)XP.
