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 a ccess 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.

Using the CLI To Disable or Re-Enable Stacking
In the default configuration, stacking is enabled on the Procurve Switch
4108GL. You can use the CLI to disable stacking on these switches 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, a nd 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, Me mber, 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 y ou 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 swit ch as the primary VLAN. (See “Which VLAN
Is Primary?” on page 14-7.)
When using stacking in a multiple-VLAN environment, the following criteria
applies:
