This article explains how to identify the NSRP state if the device is on Master, Backup or Inoperable.
The simplest way to tell the device status is to view the firewall prompt. The state is displayed in parentheses after the hostname: M, B or I.
For example:
- SSG550(M) means master
- SSG550(B) means Backup
- SSG550(I) means Inoperable mode
It is helpful to understand the status of the VSD. The 5 states are listed below:
- Master – The state of a VSD group member that processes traffic sent to the VSI.
- Backup – The state of a VSD group member that monitors the status of the master and takes over should the master fail.
- Initial – The transient state of a of a VSD group member while it joins a VSD group.
- Inoperable – The state of a VSD group member after a system check determines that the device has an internal problem or a network connection problem (link down). Refer to KB11338 for more information.
- Ineligible – The state that an administrator purposefully assigns to a VSD group member so that it cannot participate in the election process. This state is commonly used during upgrades. Refer to KB11477 for more information.
To further verify the status, follow the steps below:
1. Enter the command
'get nsrp cluster' to get the local unit ID.
In the output below, the local unit ID is 8345472.
SSG550(M)-> get nsrp cluster
cluster id: 3, no name
local unit id: 8345472
active units discovered:
index: 0, unit id: 8345472, ctrl mac: 0005857f5787, data mac: 0005857f5787
index: 1, unit id: 10923520, ctrl mac: 00121ea6ae07, data mac: 00121ea6ae07
total number of units: 2
SSG550(M)->
2. Then enter '
get nsrp vsd-group' to check the VSD status of that local unit ID. In the output below, the local device unit ID 8345472 is master.
SSG550(M)-> get nsrp vsd-group
