HP 2500 manual Using the CLI To Disable or Re-Enable Stacking, Transmission Interval

HP ProCurve Stack Management

Note that in the above example (figure 9-37) 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 ProCurve Switch 2512 and 2524. 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, 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 “Which VLAN Is Primary?” on page 9-53.)

When using stacking in a multiple-VLAN environment, the following criteria applies:
