Table 56: Resolved Issues, Platform-Specific and Feature PDs
PD Number Description
General
PD4-1191404997 When disabling and enabling a BGP peer with 15,000 routes multiple times, an assertion
failure occurs and the BGP process crashes with signal 6.
PD4-1202538501 When BFD transmit intervals are set to 100 ms for 50 BFD sessions, the sessions are
not formed and the switch crashes.
PD4-1221696686 ExtremeXOS software is unable to upgrade an ExtremeXOS software license to any
switch that has a serial number beginning with 0953x-xxxx using the enable license
file <license-file.xlic> command.
Workaround: Enable the license by running the enable license < key > command.
BlackDiamond 8800 Series Switch
PD4-1193953108,
PD4-1191020319
When a 10M SFP+ passive copper cable is inserted into an 8900-10G24X-c module, it is
detected as a 1 Gbps optic instead of a 10 Gbps optic and the port is incorrectly
reconfigured for 1 Gbps operation. SFP+ passive copper cables of other lengths do not
experience this problem.
BlackDiamond 10800 Series Switch
PD4-1202578215 Process LLDP crashes with signal 6 and the DUT reboots when the IdMgr is enabled
with 180 LLDP neighbors, and an SNMP Walk is performed on lldpRemTable.
BlackDiamond 12800 Switch
PD4-1195687987 The BGP process crashes with signal 6 while trying to delete a VLAN from a user
created VR in MPLS-VR.
Workaround: Disable BGP prior to deleting the VLAN and enable graceful restart on BGP.
PD4-1198343901 By default, Kerberos authentication uses UDP to transmit data. UDP provides no
guarantee that a packet sent along the network will reach its destination intact. In
addition, the UDP Kerberos protocol may cause the "KRB_ERR_RESPONSE_TOO_BIG:
Response too big for UDP, retry with TCP" error (that is, the size of a ticket is too large
to be reliably transmitted by UDP). In some cases, the client fall back from UDP to TCP
Kerberos request may affect ExtremeXOS Kerberos snooping.
Workaround: This issue is not seen if Kerberos packets are sent either through UDP or
with TCP Kerberos only. It is recommended that the client use either TCP or UDP for a
Kerberos request on the client side (reference: http://support.microsoft.com/kb/244474).
BlackDiamond 20800 Series Switch
PD4-815808567 After refreshing a large ACL, the ACL counter is hit even though the match condition is
not met.
PD4-1158486259 In a VPLS configuration with RSVP redundant paths, disabling and enabling a primary
path link results in traffic flowing asymmetrically between the primary and secondary
paths.
PD4-1195690741 A DUT crashes when configuring ARP pending entries to a lower number while the DUT
contains additional numbers of pending entries.
PD4-1213977743 The delay shown in the output of the show cfm segment frame-delay
statistics command is incorrect by a decimal.
