Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: This crash will occur if an invalid protocol or service field is provisioned in a Cisco
VSA. However, even when valid protocols or services are used, it is possible that certain
enumeration walking code may also trigger a crash. However, Cisco has not been able to validate
that situation. As a consequence, when using branches such as Cisco IOS Release 12.2(33)SB or
Release 12.2XNC, without this fix, it is critical that no invalid Cisco VSA be used.
CSCta30344
Symptoms: Relay information option is not verified in the downstream DHCP packets.
Conditions: This happens only when option 82 insertion is configured at the interface configuration
mode.
Workaround: Configure option 82 in global configuration mode.
CSCta34908
Symptoms: Following error message is displayed:
SPA_EEPROM-3-RPC_FAILED: Failed to send RPC message to read EEPROM of SPA in subslot
7/0 - rpc timeout error after fpd upgrade.
Conditions: This error usually seen following reload of the SPA after FPD upgade of SPA.
Workaround: Perform an online insertion and removal (OIR) of SPA. If that does not work, then
reload line card.
CSCta42753
Symptoms: Following reload or reseat of Protect LC in ADM TRuepointR 6400,
SPA-2OC3-POS/SIP400/SRD2 reports "Received Alarm: L-AIS" on the PROTECT port of a 1+1
APS group when an inline SONET analyzer attached to same wire reports no L-AIS is present on
the wire.
Conditions: L-AIS is recovered by an STE via looking for K2 = 0x07 for 5 consecutive frames.
A Cisco POS interface with "pos ais-shut" will transmit L-AIS when interface is shutdown. Without
"pos ais-shut" the interface continues to send valid SONET frames toward the STE/LTE.
Workaround: Remove/reinsert the cable on CPE to clear the alarm.
CSCta43713
Symptoms: Port-channel on interface of ES+, a line card reload causes memory leak on "RPC
pagp_switch_sp2mp" and "QM_VLOU_MAP". It loses about 748 bytes per policy-map attached on
interface.
Conditions: Occurs on a Cisco 7600 series router with policy-map configured on port channel
interface.
Workaround: There is no workaround.
CSCta46650
Symptoms: The console gets stuck when the show arp command is executed and "esc" is pressed to
stop viewing the whole output.
Conditions: The symptom is observed with 512 ARP sessions on the system and set term len equal
to 20.
Workaround: There is no workaround.
CSCta46653
Symptoms: In ES+ line cards with link daughter card versions less than .200, there is a possibility
of the line card crash when an SFP module is removed and inserted.
Conditions: Occurs under normal operating conditions.
