Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S3
Now the Path messages on this router come via a different incoming interface. This router had ip
rsvp signalling refresh reduction enabled.
We can now see the that this router stops sending Refresh reduction messages downstream. After
some time, the downstream router will say that it has missed the refreshes and then after some time
(around 5 minutes), the tunnel will be down.
CSCsf04035
Symptoms: Upon an SSO switchover, on the new active RP, the MFR interface shows the default
bandwidth value instead of the actual bandwidth, which is based on the available bundle links.
Conditions: This symptom is observed on a Cisco 7600 router that is running 12.2SR software and
on a Cisco 12000 series Internet router that is running 12.0SY software.
Workaround: Recycle the MFR interface to reset the bandwidth to the correct value.
CSCsf32449
Symptoms: A Sup720 Multicast-VPN (MVPN) PE router may not advertise its mdt prefix (BGP
vpnv4 RD-type 2) after reloading.
Conditions: This symptom is observed on a Sup720 MVPN PE router.
Workaround: Use the clear ip /jointfilesconvert/415844/bgp command after reloading.
CSCsg00102
Symptoms: SSLVPN service stops accepting any new SSLVPN connections.
Conditions: A device configured for SSLVPN may stop accepting any new SSLVPN connections,
due to a vulnerability in the processing of new TCP connections for SSLVPN services. If the debug
ip tcp transactions command is enabled and this vulnerability is triggered, debug messages with
connection queue limit reached will be observed.
This vulnerability is documented in two separate Cisco bug IDs, both of which are required for a
full fix CSCso04657 and CSCsg00102.
CSCsg02387
Symptoms: A time-out occurs when you enter an SNMP command for an IPv6 interface. However,
you can ping the IPv6 interface.
Conditions: This symptom is observed on a Cisco 7200 series but is platform-independent.
Workaround: There is no workaround.
CSCsh97579
Cisco devices running affected versions of Cisco IOS Software are vulnerable to a denial of service
(DoS) attack if configured for IP tunnels and Cisco Express Forwarding. Cisco has released free
software updates that address this vulnerability. This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20090923-tunnels.shtml.
CSCsi57031
Symptoms: On a pseudowire that is configured on an OC-12 ATM interface, when you delete the
oam-ac emulation-enable command, enter the write memory command, and then initiate an SSO
switchover, the new standby PRE continues to reboot because of a configuration mismatch with the
new active PRE.
Conditions: This symptom is observed on a Cisco 10000 series when the new active PRE has the
oam-ac emulation-enable command in its configuration but the new standby PRE does not, causing
a configuration mismatch. The symptom may not be platform-specific.
