Application scenarios Remarks
Less than 90
seconds
Connected to servers, storage
devices, or third-party switches.
According to FC-BB-5, the upper limit of the FKA
advertisement interval value is 90 seconds. In this
scenario, an FCF switch or NPV switch operating in
standalone mode or in IRF mode but without subordinate
switches will experience FCoE traffic disruption during
an ISSU reboot for the following reasons:
• The ISSU reboot takes more than 225 (2.5*90)
seconds.
• The peer deletes the virtual link for failing to receive
unsolicited Discovery Advertisements within 225
seconds.
You must also adjust the FKA advertisement interval
value on the upstream FCF switch to ensure service
continuity in the following cases:
• Active/standby switchover on an NPV switch .
• ISSU reboot on an IRF member NPV switch with
subordinate switches.
You must do that for the following reasons:
• The FKA advertisement interval value configured on
the NPV switch affects only its VFC interfaces in F
mode and connected ENodes.
• Its VFC interfaces in NP mode use the FKA
advertisement interval value learned from the
upstream FCF switch.
60–90 seconds
Active/standby switchover on
the switch takes more than 2.5 x
60 seconds because of the
amount of FCoE configuration.
ISSU reboot on an IRF member
switch with subordinate
switches takes more than 2.5 x
60 seconds because of the
amount of FCoE configuration.
For more information about ISSU, see Fundamentals
Configuration Guide.
300–600
seconds
ISSU reboot on a switch
operating in standalone mode
or in IRF mode but without
subordinate switches and
connecting to no nodes.
During an ISSU reboot on a switch operating in
standalone mode or in IRF mode but without subordinate
switches, the switch cannot send unsolicited Discovery
Advertisements or keepalive frames.
