When you changed the settings, you rebooted the all box, right ?

On my OP, I mentioned that I have two supervising engine on SSO mode which
is:
1 5 Route Switch Processor 720 10GE (Activ RSP720-3CXL-10GE
2 5 Route Switch Processor 720 10GE (Hot) RSP720-3CXL-10GE
Though, the second one was added much later. I was running
c7600rsp72043-adventerprisek9-mz.153-1.S1.bin before but now I updated it to
c7600rsp72043-adventerprisek9-mz.153-3.S3.bin.
Running "sh mls cef max", I see:
#sh mls cef maximum-routes
FIB TCAM maximum routes :
=======================
Current :-
-------
IPv4 + MPLS - 512k (default)
IPv6 + IP Multicast - 256k (default)
User configured :-
---------------
IPv4 - 768k
MPLS - 24k
IPv6 + IP Multicast - 112k (default)
Upon reboot :-
-----------
IPv4 - 768k
MPLS - 24k
IPv6 + IP Multicast - 112k (default)
BUT "remote command switch show mls cef max", I see:
FIB TCAM maximum routes :
=======================
Current :-
-------
IPv4 + MPLS - 512k (default)
IPv6 + IP Multicast - 256k (default)
Could this mean that the two sups are not sync? Here is the output of show
redundancy states:
#sh redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 1
Redundancy Mode (Operational) = sso
Redundancy Mode (Configured) = sso
Redundancy State = sso
Maintenance Mode = Disabled
Communications = Up
client count = 169
client_notification_TMR = 30000 milliseconds
keep_alive TMR = 9000 milliseconds
keep_alive count = 1
keep_alive threshold = 18
RF debug mask = 0x0
