5. Use show server backup and show log to obtain the Brocade Virtual ADX status in the Hot
Standby HA configuration.
The following screen shots display the different stages of reload and show how a Brocade Virtual
ADX comes up in a Hot Standby HA configuration.
Virtual ADX-A#show server backup
Server Backup port = 3 <----------- Sync-link port on this Brocade Virtual ADX
Backup group id = 0
Switch state = Standby
SLB state = 1 <-------------------- Start of the SLB sync. Five stages: 0>1>2>3>4>0
Share MAC = Off <------------------ Indicates whether promiscuous mode is configured.
Peer sync state = 0
SLB Partner MAC valid= 0 <------------- 0 indicates the MAC below is not valid
SLB Partner MAC = 0000.0000.0000 <----- Peer Brocade Virtual ADX MAC
SLB Partner HA sync port MAC = 0000.0000.0000
SLB Partner VLAN ID = 999 <--------- VLAN used to perform heartbeat between Brocade Virtual ADX
SLB Partner port cnt = 0
SLB Backup preference = 0 minutes
SLB Backup timer = 1000 milliseconds
Active attempts = 0
Transitions, activates = 0, standby = 0
Pdus sent = 0, Pdus recv = 0
Null Pdus sent = 0, Mac pdu sent = 0
No pdus = 0, no port maps = 0
Routers ports = 0, Partner Routers ports = 0
Server ports = 0, Partner Server ports= 0
My Cost = 9, Peer Cost = 10
Brocade Virtual ADX A is running in single-box mode, because Brocade Virtual ADX B is not yet
discovered.
Virtual ADX-A#show server backup
Server Backup port = 3
Backup group id = 0
Switch state = Active <------------ Assumes Active since no peer was detected by sending null PDUs
SLB state = 0<-------------------- State returns to 0
Share MAC = Off
Peer sync state = 0
SLB Partner MAC valid= 0
SLB Partner MAC = 0000.0000.0000<-- Still did not find peer and entry remains all zeros
SLB Partner HA sync port MAC = 0000.0000.0000
SLB Partner VLAN ID = 999
SLB Partner port cnt = 255
SLB Backup preference = 0 minutes
SLB Backup timer = 1000 milliseconds
Active attempts = 0
Transitions, activates = 0, standby = 0
Pdus sent = 0, Pdus recv = 0
Null Pdus sent = 215, Mac pdu sent = 0
No pdus = 0, no port maps = 0
Routers ports = 0, Partner Routers ports = 0
Server ports = 1, Partner Server ports = 0
