TABLE 35
Field descriptions for show server backup command
Field
Description
Switch state
Indicates whether this Brocade Virtual ADX is the active or the standby Brocade Virtual
ADX. The state can be one of the following:
•
Active
•
Standby
SLB state
When a Brocade Virtual ADX comes up in the Hot Standby HA configuration, it requests
the following information from the peer Brocade Virtual ADX:
•
Port map information
•
MAC information
•
Server mapping information
•
Session information (Fail-over session sync)
After this processing is completed, the Brocade Virtual ADX goes to the "SLB
synchronization complete" state.
This field displays one of the following states during the request for peer information:
•
SLB_SYNC_COMPLETE state (Value = 0). All synchronization requests from the local
Brocade Virtual ADX have been sent to the peer Brocade Virtual ADX. This process is
now complete (value = 0).
•
SLB_SYNC_REQ_MAP state (Value = 1). Denotes the local Brocade Virtual ADX is
requesting the peer Brocade Virtual ADX for port map information.
•
SLB_SYNC_REQ_MAC state (Value = 2). Denotes the local Brocade Virtual ADX is
requesting the peer Brocade Virtual ADX for MAC information.
•
SLB_SYNC_REQ_SERVERS state (Value = 3). Denotes the local Brocade Virtual ADX
is requesting the peer Brocade Virtual ADX for Server mapping.
•
SLB_SYNC_REQ_L4 state (Value = 4). Denotes the local Brocade Virtual ADX is
requesting the peer Brocade Virtual ADX for session synchronization (fail-over
session sync).
