Displaying VRRP Group Statistics
The VRRP Group Statistics page displays counters for VRRP protocol events and
errors that have occurred on a specific VRRP interface.
Field Attributes
•
VLAN ID
– ID of a VLAN configured with an IP interface. (Range: 1-4093; Default: 1)
• VRID – VRRP group identifier. (Range: 1-255)
• Times Become Master – Number of times this router has transitioned to master.
• Received Packets – Number of VRRP advertisements received by this router.
• Error Interval Packets – Number of VRRP advertisements received for which the
advertisement interval is different from the one configured for the local virtual router.
•
Authentication Failures
– Number of VRRP packets received that do not pass the
authentication check.
•
Error IP TTL Packets
– Number of VRRP packets received by the virtual router with
IP TTL (Time-To-Live) not equal to 255.
• Received Priority 0 Packets – Number of VRRP packets received by the virtual
router with priority set to 0.
• Error Packet Length Packets – Number of packets received with a packet length
less than the length of the VRRP header.
• Invalid Type Packets – Number of VRRP packets received by the virtual router
with an invalid value in the “type” field.
• Error Address List Packets – Number of packets received for which the address
list does not match the locally configured list for the virtual router.

•
Sent Priority 0 Packets
– Number of VRRP packets sent by the virtual router with

participating in VRRP, and is used to quickly transition a backup unit to master
mode without having to wait for the master to time out.
