(host) #show stacking members

 

Member status: Active, Stack Id: 001a1e087b004fcee152

 

Stack uptime: 3 minutes 55 seconds

 

Id Role MAC Address Priority State Model Serial

 

-- ---- ----------- -------- ----- ----- ------

 

0 * Primary 001a.1e08.7b00 128 Active ArubaS2500-48T BK0000016

 

1 Linecard 001a.1e08.7b80 128 Active ArubaS2500-48T BK0000018

 

2 Secondary 001a.1e08.7c00 128 Active ArubaS2500-48T BK0000015

 

3 Linecard 001a.1e08.7c80 128 Active ArubaS2500-48T BK0000014

In the above ArubaStack of four members, if Linecard member 1 is down and to be replaced, complete the following steps:
 
1. Verify stacking members. Member 1 is down and the status will be displayed as Away and the role will be Unknown.
 
(host) #show stacking members
Member status: Active, Stack Id: 001a1e087b004fcee152
Stack uptime: 11 minutes 16 seconds
Id Role MAC Address Priority State Model Serial
-- ---- ----------- -------- ----- ----- ------
0 * Primary 001a.1e08.7b00 128 Active ArubaS2500-48T BK0000016
1 Unknown 001a.1e08.7b80 128 Away ArubaS2500-48T BK0000018
2 Secondary 001a.1e08.7c00 128 Active ArubaS2500-48T BK0000015
3 Linecard 001a.1e08.7c80 128 Active ArubaS2500-48T BK0000014

 

2. To replace member 1, clear the stacking database from the ArubaStack using the clear command as shown below.
 

 

(host) #clear stacking member-id 1

 

Member-id: 0

 

------------

 

Deleting Member-id: 1

 

Member-id: 2

 

------------

 

Deleting Member-id: 1

 

Member-id: 3

 

------------

 

Deleting Member-id: 1

 

 

3. Stacking database will be cleared and member 1 will not be visible in the show stacking command as shown below.
 
(host) #show stacking members
Member status: Active, Stack Id: 001a1e087b004fcee152
Stack uptime: 18 minutes 29 seconds
Id Role MAC Address Priority State Model Serial
-- ---- ----------- -------- ----- ----- ------
0 * Primary 001a.1e08.7b00 128 Active ArubaS2500-48T BK0000016
2 Secondary 001a.1e08.7c00 128 Active ArubaS2500-48T BK0000015
3 Linecard 001a.1e08.7c80 128 Active ArubaS2500-48T BK0000014
 
 
4. Physically replace member with a new unit. The new unit will transition from an invalid unit Id shown by (?) and eventually be assigned the lowest stack-id available in the existing ArubaStack. In this case the new unit will be assigned unit ID 1.
 
(host) #show stacking members
Member status: Active, Stack Id: 001a1e087b004fcee152
Stack uptime: 29 minutes 15 seconds
Id Role MAC Address Priority State Model Serial

2 Secondary 001a.1e08.7c00 128 Active ArubaS2500-48T BK0000015
3 Linecard 001a.1e08.7c80 128 Active ArubaS2500-48T BK0000014
? Linecard 001a.1e08.7ac0 128 Active ArubaS2500-48T BK0000019
 
(host) #show stacking members

The ArubaStack features allows the user to replace one or more members of a ArubaStack without bringing down the complete ArubaStack. Following are best practices, based on dynamic and preset ArubaStack configurations. When replacing a unit with another unit that is not factory default, it is recommended to restore the unit to factory default
as shown below.

(Aruba) #restore factory_default stacking
All configuration and stack settings will be restored to
factory default on this member after reload.
Press 'y' to proceed with reload: [y/n]: y
System will now restart
