Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: There is no workaround.
• CSCta58194
Symptoms: Router crashes with max-entries of NAT translations limit imposed.
Conditions: With ip nat max-entries limit <> configured and greater than limit number of flows
passed through the NAT router, crash is seen when the above limit configuration is removed and a
large amount of translations are created.
Workaround: There is no workaround.
• CSCta61663
Symptoms: Cisco 7600 SPA-1XCHSTM1/OC3 SPA does not use the configuredn etwork-clock
source as the reference for the T1/E1.
Conditions: The SPA-1XCHSTM1/OC3 SPA is configured to use the internal clock for timing of the
T1/E1. The network-clock is configured on the Cisco 7600 to use the reference from an ATM OC3
interface.
Workaround: There is no workaround.
• CSCta65610
Symptoms: When configuring an OSPF sham-link between two PEs also used for multicast VPN,
RPF check for the source of a multicast stream points to the physical interface used by the sham-link
instead of the tunnel.
Conditions: Configure two PEs to run MVPN and create a sham-link between them. Remote routes
that are learned through the sham link will not have an MDT tunnel.
Workaround: There is no workaround. Prefixes must be learned through i-BGP.
• CSCta68856
Symptoms: Policy map with multiple MAC ACL filters matches only the traffic with the first MAC
ACE in the ACL.
Conditions: Occurs on a Cisco 7600 series router with ES+ linecard, and with policy map with MAC
ACL configured on ES+ linecard interface.
Workaround: There is no workaround.
• CSCta69232
Symptoms: Resilient Ethernet Protocol (REP) will not converge if REP is configured over
switchport and vlan dot1q tag native is enabled.
Conditions: In this case, the REP PDUs will be sent as tagged packets.
Workaround: There is no workaround.
• CSCta77105
Symptoms: Hierarchical service policy is not attached to multilink on SIP-200
Conditions: When the hierarchical service-policy is applied on the interface on sip1 or sip2, it is
rejected.
Workaround: There is no workaround.
• CSCta77747
Symptoms: If a ES+ port is configured as switchport trunk and the Cisco 7600 is supposed to route
the traffic between the vlans carried in the trunk, routing is not happening.
Conditions: Occurs when ES+ ports are configured as switchports, such as follows:
