Stack Management for the Series 3400cl and 6400cl Switches 
Configuring Stack Management 
Note that in the above example (figure 13-37) you cannot use the public 
community through the Commander to access any of the Member switches. 
For example, you can use the public community to access the MIB in switches 
1 and 3 by using their unique IP addresses. However, you must use the red or 
blue community to access the MIB for switch 2. 
snmpget < MIB variable > 10.31.29.100 blue@sw2 
Using the CLI To Disable or Re-Enable Stacking 
In the default configuration, stacking is enabled on the switch. You can use 
the CLI to disable stacking on the switch at any time. Disabling stacking has 
the following effects: 
■  Disabling a Commander:  Eliminates the stack, returns the stack Mem-
bers to Candidates with Auto Join disabled, and changes the Commander 
to a stand-alone (nonstacking) switch. You must re-enable stacking on the 
switch before it can become a Candidate, Member, or Commander. 
■  Disabling a Member: Removes the Member from the stack and changes 
it to a stand-alone  (nonstacking) switch. You must re-enable stacking on 
the switch before it can become a Candidate, Member, or Commander. 
■  Disabling a Candidate: Changes the Candidate to a stand-alone (non-
stacking) switch. 
Syntax:  no stack  (Disables stacking on the switch.) 
stack  (Enables stacking on the switch.) 
Transmission Interval 
All switches in the stack must be set to the same transmission interval to help 
ensure proper stacking operation. HP recommends that you leave this param-
eter set to the default 60 seconds. 
Syntax:  stack transmission-interval < seconds > 
Stacking Operation with Multiple VLANs Configured 
Stacking uses the primary VLAN in a switch. In the factory-default configura-
tion, the DEFAULT_VLAN is the primary VLAN. However, you can designate 
any VLAN configured in the switch as the primary VLAN. (See 
“The Primary 
VLAN” on page 2-43.) 
When using stacking in a multiple-VLAN environment, the following criteria 
applies:
