Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 17
OSPF
Problem:
Upgrading the switch from a Release 3.1 or other previous release to Release
4.0.1 may cause the loss of your virtual link configuration.
Workaround: After upgrading and resetting the switch, view your running
configuration to ensure that virtual links are intact. (To view your running
configuration, click Running Config in the CLI Configuration section of the Web
Agent.) If the virtual link configuration is lost, reconfigure the virtual links.
NOTES:
• When the Cajun P550 first boots up as an ABR or ASBR, it may send an ASBR
advertisement for itself. This advertisement is later flushed by the system.
• When changing the OSPF Router ID, the Cajun P550R does not immediately flush
the advertisements with the original Router ID. Instead these advertisements will be
flushed when they are aged from the database.
• When a virtual link is created on the Cajun P550R router, the router cannot detect if
the remote router is an ABR to area 0.0.0.0.
• There may be a loss of Web connectivity for about 10 seconds during LSA updates in
a large OSPF network.
Piggyback Ports
NOTE:
If a router port for intelligent multicasting is mirrored with a piggyback port, the
piggyback port is listed instead of the router port.
RMON
NOTE: On Gigabit Ethernet port, under heavy utilization, 30 minute RMON stats always
show utilization as 0.
