Chapter 8 Interface and Subinterface Management
Ethernet Interface Management Window
HSRP Tab
The following areas are available on the HSRP tab of the Ethernet Interface Management window:
•
HSRP
• Secondary IP
HSRP
The HSRP area provides the following information:
•
HSRP Group Table—Describes HSRP groups deployed on an interface.
Note There may be multiple groups deployed on an interface. Using a group number on one logical
or physical interface does not preclude using it on another.
• Virtual IP—Primary virtual IP address of the HSRP group. If this address is not configured, the
agent attempts to discover the virtual address through a discovery process which scans the hello
messages.
• Preempt—If enabled, the current router attempts to overthrow a lower priority active router and
attempt to become the active router. If disabled, this router becomes the active router only if there
is no such router or the active router fails.
– true—preempt enabled.
–
false—preempt disabled.
• Delay Minimum—Time difference (in seconds) between a router power up and the time it can start
preempting the currently active router. This value is only applicable when preemption is enabled.
•
Priority—Priority value that prioritizes a potential hot standby router. The range is 1 to 255, where
1 indicates the lowest priority and 255 indicates the highest priority. The default priority value is
100. The router in the HSRP group with the highest priority value becomes the active router.
• Hello Interval—Hello interval in milliseconds. If this value is not configured, it can be learned from
the active router.
• Hold Interval—Hold interval in milliseconds. If this value is not configured, it can be learned from
the active router.
• Configure—Launches the Ethernet Interface Management - Configure HSRP Group window to add
and remove an explicit HSRP group configuration to the interface. Adding deploys an HSRP group
on the interface. The HSRP group may optionally be assigned a primary IP address. If no address is
explicitly assigned, the device attempts to discover the virtual IP address from the active server
using Hello messages.
