Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Further Problem Description: Few bootup tests fail when on 6816 card when the multirouters are
reloaded. On failure, the ports are put in error disabled state. Failure cause has been root caused to
usage of reserved diag vlans in the configs. Please refer the link mentioned below.

S1.html
switchport dot1q: Do not enable the reserved VLAN range (1006 to 1024) on trunks when
connecting a Catalyst 6500 series switch running Cisco IOS software on both the supervisor engine
and the MSFC to a Catalyst 6500 series switch running Catalyst software. These VLANs are
reserved in systems running Catalyst software. If enabled, systems running Catalyst software may
error disable the ports if there is a trunking channel between these systems
When the diag vlans (1006 to 1011, 4094 to 4089) are used, there could be diag failures at some
random cases. Please do not enable the reserved vlans.
• CSCsu31954
Symptoms: A router reloads.
Conditions: Under certain crypto configurations with NetFlow also configured, the router will
reload when required to fragment CEF-switched traffic on a Cisco 7200 router.
Workaround: There is no workaround.
• CSCsu35597
Symptoms: Renaming a directory gives error message.
Conditions: This happens on a Cisco router running Cisco IOS Release 12.4(20)T1.fc2 image
Workaround: There is no workaround.
• CSCsu35624
Symptoms: When a private VLAN is configured on a VTPv3 server and then deleted, the update
message on a peer VTPv3 client can cause a stack overflow for VLAN manager process and crash.
Conditions: Occurs in a Cisco 7600 running Cisco IOS Release 12.2(33)SRD.
Workaround: There is no workaround.
• CSCsu36697
Symptoms: The line card reloads when a line card online insertion and removal (OIR) is performed.
It does not happen consistently.
Conditions: This occurs when an empty policy is present.
Workaround: There is no workaround.
• CSCsu36709
Symptoms: A router may unexpectedly reload.
Conditions: The symptom is observed specifically with a configuration of Enhanced Interior
Gateway Routing Protocol (EIGRP) that is used to redistribute BGP routes. Plain EIGRP is not
affected.
Workaround: Do not use EIGRP to redistribute BGP.
• CSCsu37205
Symptoms: BGP dampening under VPNv4 may cause router crash.
Conditions: Occurs when BGP dampening is enabled on VPNv4 address family, but not on
individual IPv4 VRF<VRF-name>address-family.
