Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S
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.
• CSCed54444
Symptoms: A Cisco 10000 series functioning as a LAC may become very busy and start queueing
up the incoming L2TP packets from an LNS, causes the middle buffer to become exhausted and
eventually use all available IO memory. Malloc failures with tracebacks can be seen in the log.
Conditions: This symptom is observed when disconnecting L2TP sessions at 200 calls per second
or more.
Workaround: There is no workaround.
• CSCed77666
Symptoms: SAA RTR key-chain authentication may fail with the following RTT responder:
authentication failure
Conditions: This symptom is observed when SAA is using a key chain which has a key ID that has
a value larger than 255.
Workaround: Ensure that the value of the key ID does not exceed 255.

Workaround 1: There is no workaround.
Symptom 2: The ifOperStatus SNMP object may return “DOWN.”
Condition 2: This symptom is observed when HDLC encapsulation and the down-when-looped
command are configured.
