Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S2
Alternate Workaround: Remove and re-add the xconnect.
• CSCso89427
Symptoms: When a router reloads, the line protocol on serial interfaces will go down.
Conditions: This symptom is observed when bringing up the SPA-1XCHSTM1/OC3 or
SPA-2XCT3/DS0 with a scaled configuration that has serial interfaces on all the T1s.
Workaround: There is no workaround.
• CSCso89794
Symptoms: Spurious accesses are seen when SNMP queries are performed on the router.
Conditions: This symptom occurs if SNMP queries like “snmpwalk -v2c 7.42.19.43 public
.1.3.6.1.4.1.9.3.6.13.1” are performed on the router. Spurious accesses are seen.
Workaround: There is no workaround.
• CSCso92635
Symptoms: The line card on a Cisco 10720 resets when an IP phone is connected. The
“%TOASTER-2-FAULT: T1 Exception summary:” message appears.
Conditions: The line card to which the Cisco Call Manager is connected to a Cisco 10720 crashes
when an IP phone is connected to the network.
Workaround: The recommended approach is to upgrade the Cisco IOS software.
• CSCso93957
Symptoms: New T1s cannot be provisioned on a CT3 SPA.
Conditions: When a customer tries to create a new T1 on one of the controllers of a CT3-SPA that
is inserted into a SIP-401, the following errors are displayed:
Router(config-controller)# t1 15 channel-group 7 timeslots 1-24
%Failed to configure channel group
Router(config-controller)#

Workaround: There is no workaround.
• CSCso93959
Symptoms: Newer SDRAM devices on the 2- and 4-port OC48 POS/RPR SPA require an additional
initialization sequence as recommended by the vendor. Without this new initialization sequence,
packets that go through the transit buffer in RPR/SRP mode or in subscription mode may get
corrupted, or packet loss may occur.
Conditions: Card initialization after inserting the SPA or removing an unpowered shutdown.
Workaround: Perform an OIR on the SPA.
Customers are advised to upgrade to the newer image with this new initialization sequence. Newer
software will be backward compatible with older SPA boards.
• CSCsq02826
Symptoms: The MDFS state of the line card stays in a “disabled” state, which may lead to multicast
traffic being punted to the RP.
