Caveats
Symptom: An FCSP-ESP enabled (encrypted) port that was working fails to come up after
ISSU/ISSD followed by link flap.
ISSU/ISSD followed by link flap.
Condition: This issue only affects FCSP encrypted ports on MDS 9700 DS-X9448-768K9 and MDS
9500 DS-X9248-256K9 and DS-X9232-256K9 switching modules after an ISSU or ISSD to an
affected version of NX-OS.
9500 DS-X9248-256K9 and DS-X9232-256K9 switching modules after an ISSU or ISSD to an
affected version of NX-OS.
Workaround: Only a switch reload will recover from this situation. The switch must be running a
fixed release of NX-OS (NX-OS 6.2(11) or above) before the reload to prevent the issue from
recurring after recovery.
fixed release of NX-OS (NX-OS 6.2(11) or above) before the reload to prevent the issue from
recurring after recovery.
None of the following steps alone will not recover the port functionality:
–
Shut/no-shut the affected port.
–
Reloading the affected linecard.
–
Removing the FCSP configuration and re-configuring FCSP.
–
Upgrading to NX-OS 6.2(11) or above.

Symptom: An ISL connected over a DWDM path does not reach link up state.
Condition: This issue only applies to MDS 9700 DS-X9448-768K9 modules used with some
DWDM vendors.

Workaround: None.
Further Problem Description: show interface shows the link in "Link failure or not-connected"
with OLS/LRR and NOS increasing in both directions.

Symptom: An ISL does not initialize quickly across a DWDM connection. The link can take
minutes, hours or even days to connect. Once connected, it is stable.

Symptom: MDS fabric switch running in NPV mode fails to generate port-monitor alerts.
Condition: Applies to all MDS fabric switches running in NPV mode using port-monitor.
Applies to all versions prior to NX-OS 6.2(13).
Will occur only in the following conditions:
- After one or more upstream NP or TNP ports goes down and then back up.
- For each (T)NP port that flaps, one F port at the end of the range of ports
will no longer be scanned for port-monitor counter events. For example, if the
(T)NP port fc1/1 flaps then the last F port being used(ex. fc1/48) will no
longer be scanned for port-monitor counter events.
Workaround: There are two workarounds, one temporary and one permanent:
1 - Contact the TAC and they can assist with killing the port-monitor process. Once the port-monitor
process restarts, all ports will be once again scanned.
process restarts, all ports will be once again scanned.
