Release Notes for the Passport 8600 Release 3.7.6
• Match Community/AS Path only works in OSPF redistribution when the
same route policy is coupled with BGP. If you do not need this BGP
redistribution, you may choose to mark its state as disabled. (Q00693853,
Q00173743-01)
• The maximum limit of “Max-prefix” from the command:
config ip bgp neighbor <neighbor IP>
is shown as 2147483647, but the actual value is 999999. (Q00915249)
High Availability (HA) mode
• The following protocols are NOT currently supported in HA mode:
— ATM and POS modules
— WSM; however, WSM incorrectly stays online when HA-CPU is
enabled. (Q00495703)
— BGP; therefore, all redistribution parameters (policies) related to BGP are
not synchronized in HA mode. (Q00786353)
— Multicast dynamic routing protocols (DVMRP, PIM-SM, PIM-SSM,
PGM)
— VRRP Fast Advertisement Interval feature; a consistency check prevents
the feature from being enabled
— IPX routing
— SSL Acceleration module
—SDM firewall
OSPFf
• Occasionally, you may see the following message when sending link state
updates:
OSPF ERROR ospfAddToReqList
This message has no impact on the switch. (Q00861942)
• Currently, there is no alarm or trap sent if the synchronization between the 2
CPUs cannot be done. (Q00781173)
• The backup CPU does not display the correct information about the I/O
module types if the initialization of the I/O fails. (Q00799826)
