Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
• CSCsz50620
Symptoms: Bus error crash at an invalid address.
Conditions: The symptom is observed when running Cisco IOS Release 12.2(31)SB with SSS
configured.
Workaround: There is no workaround.
• CSCsz52815
Symptoms: If number of hours for statistics is increased to 10 or more after the probe is initially run
and then restarted, system crashes with memory corruption
Conditions: Occurs when the probe is started with the hours of statistics less than 10 and then
re-started with the hours of statistics greater than 9.
Workaround: There is no workaround.
• CSCsz53177
Symptoms: When running Network Load-balancing (IGMP-mode) in VLANs with PIM enabled and
static ARP entries for unicast IP to layer-2 multicast address, packet duplication will occur.
Conditions: This symptom occurs when sending unicast (non-multicast) IP packets with multicast
layer-2 destinations.
Workaround: Use non-IGMP NLB modes (unicast or multicast with static macs) or use IGMP
snooping querier instead of PIM on NLB SVIs.
• CSCsz54749
Symptoms: Router crashes.
Conditions: Occurs when configured with BGP damping and default IPv4 unicast address-family is
deleted.
Workaround: Do not delete the default IPv4 unicast address-family.
• CSCsz56805
Symptoms: Different IPs are seen on the same session between Active and Standby PRE cards and
the number of in-use IP addresses on Standby is more than that on the Active.
Conditions: The symptom is observed with the frequent connect/disconnect of sessions and when IP
addresses are allocated from the local pool.
Workaround: Reload the Standby card frequently.
• CSCsz58461
Symptoms: Configuring no negotiation auto on Gigabit interface of 2xGEv2 SPA reduces duplex
on interface to half. This causes traffic drop if traffic is bi-directional.
Conditions: Occurs when "media-type" configured on Giginterface as "SFP".
Workaround: There is no workaround.
• CSCsz59914
Symptoms: When the SAMI module is booted up, CEF is disabled by default in the PPCs. If a PPC
is configured for ISG, no static IP sessions (L2-connected or L3-routed) can come up. Even after
enabling CEF, static IP sessions still do not come up. If the PPC(s) or SAMI gets reloaded after
enabling CEF and writing the configurations into memory, sessions will come up.
Conditions: When installing/configuring a new SAMI card for ISG, static IP sessions will not come
up if CEF was disabled on bootup.
