Resolved Caveats—Cisco IOS Release 12.0(28)S6
Resolved Caveats—Cisco IOS Release 12.0(28)S6
Cisco IOS Release 12.0(28)S6 is a rebuild of Cisco IOS Release 12.0(28)S. The caveats listed in this
section are resolved in Cisco IOS Release 12.0(28)S6 but may be open in previous Cisco IOS releases.
This section describes only severity 1, severity 2, and select severity 3 caveats.
Basic System Services
• CSCdu32036
Symptoms: When you attempt to apply an access list for SNMP by entering the snmp-server
tftp-server-list command, the access list is not applied. This situation makes it possible to copy the
configuration to and from any server, regardless of the contents of the access list.
Conditions: This symptom is observed on a Cisco platform that is configured for SNMP.
The following sample configuration causes the platform to reject configuration file transfers via
SNMP from all hosts except the TFTP server that is specified in access list 5:
snmp-server tftp-server-list 5
access-list 5 permit 10.1.1.1
snmp-server community private RW 5
snmp-server tftp-server-list 5
Workaround: Apply a more general access list to restrict traffic to and from the affected platform.
Alternate Workaround: Disable the SNMP.
• CSCsb08386
Symptoms: A router crashes when you enter the show ip bgp regexp command.
Conditions: This symptom is observed on a Cisco router when BGP is being updated.
Workaround: Enable the new deterministic regular expression engine by entering the bgp regexp
deterministic command and then enter the show ip regexp command. Note that enabling the new
deterministic regular expression engine may impact the performance speed of the router.
• CSCsb98906
Symptoms: A memory leak may occur in the “BGP Router” process.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0(26)S6,
that is configured for BGP, and that has the bgp regexp deterministic command enabled.
Workaround: Disable the bgp regexp deterministic command.
IP Routing Protocols
• CSCef08797
Symptoms: A router may stop redistributing static routes into BGP.
Conditions: This symptom is observed when the static routes are inserted into the BGP table with a
network statement that uses a route map that is configured with the match as-path route-map
configuration command.
The symptom occurs because the match as-path route-map configuration command causes a
non-BGP route to be denied.
Workaround: Do not use BGP-specific match statements when you source non-BGP routes.
