– Unified ISSU support
is provided only for
non-channelized APS
IOAs. Also, unified
ISSU can proceed
only if you have not
configured APS on the
OCx/STMx ATM or
OCx/STMx POS line
modules. If you have
configured APS, a
warning message is
displayed and the
router cannot proceed
with the unified ISSU.
The unified ISSU
process for
channelized line
modules remains
unchanged.
E120 and E320
routers do not support
APS.
–
– ARP entries in the
ARP cache do not
time out because no
ARP aging occurs
during unified ISSU.
When the unified
ISSU is completed,
the ARP cache
contains the same
entries as it had
before the unified
ISSU began.
