This problem occurs even when alternate paths exist.
This could lead to premature packet drops.
Workaround: Reload the system.
CSCdp71987 On a Cisco uBR7200 series universal broadband router that is running Cisco IOS Release 12.1, the setting of max-cpe is enforced.CSCds38055 When an operation, administration, and maintenance (OAM) F5 end to end cell is received over permanent virtual circuit (PVC) configured for data (normal operation the Segmentation and Reassembly (SAR) component returns the same buffer descriptor twice; one on OAM status queue, the other.CSCds57407 On Cisco 5300 series universal access servers running Cisco IOS Release.1(3)T with pre authentication and channel-associated signalling (CAS callers may get dead air instead of a busy signal if pre authentication fails.The path segment length indicates the number of autonomous systems (ASes) in the segment.This situation occurs in topologies that include the following attributes: a hierarchy of static recursive routes bono cumpleaños canapro with varying mask lengths route aggregation using the null0 interface Workaround: Ensure that the route flaps.CSCdu49594 If a Cisco router has the same IP address configured on two interfaces where one of the interface is in shutdown state and it is configured to run a Tag Distribution Protocol (TDP Label Distribution Protocol (LDP) session, the peer may have tfib entries.If a user who is using Cisco IOS Release.1(5)T and VIP-based MQC changes to an earlier release, the MQC features will revert back to the RSP-based MQC features (this is based on the assumption that the user is using MQC features that are common.CSCdr55351 When Channel-Associated Signalling (CAS) pre authentication is enabled after Dial-In over isdn/automatic number identification (dnis/ANI) collection for E1 R2 Signalling, Cisco IOS software will not send an answer signal until it gets a response from the radius server.Workaround: Disable and then reenable the rate-limit interface configuration command.CSCdr58788 Non-Facility Associated Signalling (nfas) voice calls and Signalling System 7 (SS7) voice calls using a Cisco SC2200 signalling controller fail.
CSCds51328 If a Cisco 804 router is running Cisco IOS Release.1(3)T, isdn Layer 2 gets lost and the router will have to be reloaded to recover.
CSCdr49828 A Cisco AS5300 series access server that uses new controller cards (either 4 ports or 8 ports T1/E1) with four serial interfaces might randomly reload.
CSCdr53686 A buffer leak may occur on a Catalyst 6000 family switch with a Multilayer Switch Feature Card (msfc) or on a Cisco 7200 series router if the Server Load Balancing (SLB) feature is running.Instead, the MIP only issues an interrupt when the DSP packet queue is nearly full or mostly empty.During startup, the router displays the following error message: Secondary addresses not allowed with negotiated addresses Workaround: Reconfigure the secondary IP addresses.The show frame-relay fragment command shows no fragment count even though FRF.12 appears to be configured properly.If the remote site does not pad the frame, the packet will be dropped from the Ethernet as a runt.The caveats in this section are resolved in Cisco IOS Release 12.1(5)T6 but may be open in previous Cisco IOS releases.
CSCdu37946 Tagged virtual circuits (TVCs) and label virtual circuits (LVCs) are created, but there is no connectivity.
Because of the internal operation of the code, the receiving border router is not affected, but its iBGP peers detect the mismatch and issue a notification message (update malformed) to reset their session.
