Problems Resolved in This Release

Nortel Multiprotocol Router sustaining release Version 15.6.1.1 resolves the following issues:

Q00470542-01: When DSQMS is configured on an interface that has the Rate Limiting Option, but no

DSQMS queues are configured, packets can be dropped.

Q00804604-04: Nortel Multiprotocol Router platforms may experience a random watchdog fault. A fault

may occur on any individual slot when the slot’s continuous operational time approaches 776 days (over 2 years).

Q00951021: ‘show ppp multilink [...]’ script commands show large octet or frame counts as negative

numbers.

Q01066720: If redundant interfaces are configured for an Ethernet LAN circuit, the corresponding ifEntry

instance attribute ifPhysAddress may not always show the correct MAC address that is in use by the active interface.

Q01141761-01: If an IP Source Address is specified in an IGMP Static Forwarding Entry, it is ignored,

resulting in the inability to set an IP Policy based solely on the IP source address.

Q01155046-01: Every 48 days, the VRRP state of a Nortel Multiprotocol Router may begin to oscillate.

The symptoms are either a multicast storm of VRRP packets being produced, or the failure to send VRRP advertisements at all, even while the VRRP interface is in master state.

Q01169762: In the Passport 5430 model of Nortel Multiprotocol Router, configuring ISDN SDBs in both

slots 4 and 5 produces a fault. The fault occurs either during the dynamic configuration of the second ISDN or when you restart a configuration that is created externally. The problem is specific to this model, and for only these specific SDB slots.

Q01169770: In the Passport 5430 model of Nortel Multiprotocol Router, configuring two ISDN SDBs

using the BCC fails with the message “No slot is available for this module”. The failure occurs when you attempt to configure the second SDB, but can occur on any SDB slot.

Q01178811-01: When two or more X.25 Virtual Circuits have been configured that have the

wfLapbPktPduSize of a Permanent Virtual Circuit larger than other configured X.25 Switched or Permanent Virtual Circuits, and a series of X.25 packets is received on the Permanent Virtual Circuit which reassemble to a large client packet, the result may be the following log message: “Error in X.25 buffer pool allocation”.

Q01186866: In installations that use a redundant host to dynamically replace another host in an OSPF

domain, a changeover where the alternate host uses the same router ID to attempt to establish an adjacency results in the Nortel Multiprotocol Router not correctly recognizing the OSPF Hello from the alternate host. The symptom is the Multiprotocol Router breaks the adjacency with the original host and sends the log message “UNKNOWN NBR”, but is unable to reestablish a correct adjacency with the alternate host.
