7 Execute the
show vrrpstatus
command with the
statistics
parameter, and check the reception
status of ADVERTISEMENT packets.
• You might find that the following is registered in the reference log:
Virtual router <VRID> of <Interface Name> received VRRP
packet for which the advertisement interval is
different than the one configured for local virtual
router. In this case, if the value of <Number of packets> with bad
advertisement interval increases in the statistics, make sure
that the setting value of the ADVERTISEMENT packet-sending
interval matches between the Switch and remote device. Also make
sure that the VRRP operation mode setting matches between them.
• You might find that the following is registered in the reference log:
Virtual router <VRID> of <Interface Name> received VRRP
packet that does not pass the authentication check. In
this case, if the value of <Number of packets>
with
authentication failed increases in the statistics, make sure that
the authentication password setting is the same between the Switch
and remote device.
• You might find that the following is registered in the reference log:
Virtual router <VRID> of <Interface Name> received VRRP
packet with IP HopLimit not equal to 255. In this case, if the
value of <Number of packets> with bad ipv6 hoplimit increases
in the statistics, make sure that there is no other router between the
Switch and remote device.
• You might find that the following is registered in the reference log:
Virtual router <VRID> of <Interface Name> received VRRP
packet for which the address list does not match the
locally configured list for the virtual router. In this
case, if the value of <Number of packets>
with bad ipv6 address
increases in the statistics, make sure that the virtual IP address setting
and VRRP operation mode setting are the same between the Switch
and remote device.
• You might find that the following is registered in the reference log:
Virtual router <VRID> of <Interface Name> received VRRP
packet that does not pass the authentication check. In
this case, if the value of <Number of packets>
with bad
authentication type increases in the statistics, check whether the
authentication password setting exists in the Switch and remote
device.
• You might find that the following is registered in the reference log:
Virtual router <VRID> of <Interface Name> received VRRP
packet that length less than the length of the VRRP
header. In this case, if the value of <Number of packets> with
packet length error increases in the statistics, make sure that the
VRRP operation mode setting is the same between the Switch and
remote device.
• You might find that the following is registered in the reference log:
VRRP packet received with unsupported version number. In
this case, if the value of <Number of packets>
with invalid type
increases in the statistics, make sure that the VRRP operation mode
setting is the same between the Switch and remote device.
If ADVERTISEMENT packets are received correctly, check the remote
device.
If ADVERTISEMENT packets are not received, go to No. 8.
