Resolved Caveats—Cisco IOS Release 12.0(27)S2
Cisco IOS Release 12.0(27)S2 is a rebuild of Cisco IOS Release 12.0(27)S. The caveats listed in this
section are resolved in Cisco IOS Release 12.0(27)S2 but may be open in previous Cisco IOS releases.
This section describes only severity 1 and 2 caveats.
Basic System Services
CSCed32794
Symptoms: Executing the tftp-server slaveslot0: global configuration command, or any
configuration commands related to tftp-server being set to access flash devices on the slave, will
cause the slave to reload.
Conditions: This symptom is observed on a Cisco 7500 series router that is running Cisco IOS
Release 12.0(23)S5 but is not platform dependent.
Workaround: Configure the tftp-server to access flash devices on the master route switch processor
(RSP) only.
CSCed47820
Symptoms: The Remote Processing Time reported by an SAA probe to a VRF/VPN loopback on a
MPLS VPN PE router is too short, about 1~30ms, while the Round Trip Time that is calculated is
too large, about >100ms. When you have probes sent to both an IPv4 Loopback and a VPNv4/VRF
Loopback, you will see that the results they provide are exactly reverse to each other. For example:
router time type remote process time roundtrip delay saa_probe2ipv4 218 1
saa_probe2vpnv4 5 219
Conditions: This symptom is observed when an SAA probe is sent to VPN/VRF addresses on an
MPLS VPN PE router through a MPLS VPN network.
Workaround: There is no workaround.
CSCee55603
Symptoms: SNMP request to VRF interface on PE router should be restricted with SNMP ACL
following the snmp-server community command, but it does not work.
snmp-server community community-name [ro | rw] access-list-number
access-list access-list-number {permit | deny} address mask
Conditions: This symptom is observed in Cisco IOS Release 12.0(27)S or later releases and is
platform independent.
Workaround:
Use an SNMP Context-Based ACL, which can choose each VRF.
snmp-server community community-name [ro | rw]
snmp mib community-map community-name target-list vpn-list-name
snmp mib target list vpn-list-name {vrf vrf-name | host ip-address}
Use the snmp-server drop vrf-traffic command if you want to discard any SNMP request
through VRF.
CSCin67568
Symptoms: A Cisco device experiences a memory leak in the CDP process.
Conditions: The device sending CDP packets sends a hostname that is 256 or more characters. There
are no problems with a hostname of 255 or fewer characters.
