Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S4
Workaround: There is no workaround.
• CSCsa98777
Symptoms: An MSFC may reload when the standby Supervisor Engine 720 is inserted. Similarly,
the active Route Processor (RP) may reload when the standby RP is inserted.
Conditions: These symptoms are observed on a Cisco Catalyst switch or router when SNMP and
SSO are configured, and when the following configuration is present on the platform:
snmp mib notification-log default
snmp mib notification-log globalageout 600
snmp mib notification-log globalsize 1500
Workaround: Do not configure SSO. Rather, configure RPR+.
Alternate Workaround: Remove the SNMP MIB notification-log configuration by entering the
no snmp notification-log default command.
• CSCsb14026
Symptoms: A standby RSP reloads continuously.
Conditions: This symptom is observed on a Cisco 7500 series that is configured for SSO and that
has the snmp mib notification-log default command enabled.
Workaround: Disable the snmp mib notification-log default command.
• CSCsc14034
Symptoms: The active RP crashes during the boot process.
Conditions: This symptom is observed on a Cisco router that is configured for SSO and that has the
snmp mib notification-log default command enabled.
Workaround: Disable the snmp mib notification-log default command.
Interfaces and Bridging
• CSCsa54176
Symptoms: Spurious memory accesses are generated on a VIP when the RSP sends traffic such as
routing updates or non-dCEF switched traffic through VLAN subinterfaces.
Conditions: This symptom is observed on a Cisco 7500 series that is configured with an RSP when
the following conditions are present:
–
The router dCEF enabled.
–
802.1Q VLAN subinterfaces are configured on Fast Ethernet or Gigabit Ethernet interfaces.
–
The VLAN subinterfaces have an output service policy configured.
Workaround: There is no workaround.
• CSCsc17534
Symptoms: Unicast packets are not CEF-switched on a VIP but are fast-switched on the RP.
Conditions: This symptom is observed on a Cisco router that has a VIP only when the ingress
interface is an ISL subinterface.
Workaround: There is no workaround.
