[c-nsp] Swap of startup-config with TCAM(CEF MAX) size change

[daigo nakayama]

Hi all,


When startup-config is swapped with TCAM(CEF MAX) size change, RELOAD
of two times is needed.
It is automatically generated once of RELOAD of two times.

Can this behavior be evaded?
(I am looking for "Method of reflecting all changes with RELOAD of one time". )

(1)Before

startup-config = AAA.txt

#show run
 mls cef maximum-routes ip 1000

#show conf
 mls cef maximum-routes ip 1000

#show mls cef maximum-routes

 FIB TCAM maximum routes :
 =======================
 Current :-
 -------
  IPv4                - 1000k
  MPLS                - 8k (default)
  IPv6 + IP Multicast - 8k (default)


(2)SWAP startup-config

startup-config = AAA.txt -> BBB.txt

#copy disk0:BBB.txt startup-config

#show run
 mls cef maximum-routes ip 1000

#show conf
 mls cef maximum-routes ip 800
 mls cef maximum-routes ipv6 100


(3)1st RELOAD(manual)

#reload

 System configuration has been modified. Save? [yes/no]: no
 Proceed with reload? [confirm] yes(enter)

startup-config = BBB.txt

#show run
 mls cef maximum-routes ip 800
 mls cef maximum-routes ipv6 100

#show conf
  mls cef maximum-routes ip 800
  mls cef maximum-routes ipv6 100

#show mls cef maximum-routes

 FIB TCAM maximum routes :
 =======================
 Current :-
 -------
  IPv4                - 1000k
  MPLS                - 8k (default)
  IPv6 + IP Multicast - 8k (default)


(4)2nd RELOAD(automatic)

"Card inserted in slot x, interfaces are now online" is displayed in
the log, and RELOAD auto starts again after a few minutes.
Of course, I am not operating anything...


(5)After

startup-config = BBB.txt

#show run
  mls cef maximum-routes ip 800
  mls cef maximum-routes ipv6 100

#show conf
  mls cef maximum-routes ip 800
  mls cef maximum-routes ipv6 100

#show mls cef maximum-routes

 FIB TCAM maximum routes :
 =======================
 Current :-
 -------
  IPv4                - 800k
  MPLS                - 8k (default)
  IPv6                - 100k
  IP multicast        - 8k (default)

<note_1>
The above-mentioned value of "TCAM size" is an example, and is not accurate.

<note_2>
The following procedures... -> NG (It results similarly)

 a) "TCAM size" change by command (ip 1000 -> ip 800 / ipv6 100)
 b) startup-config swap (AAA.txt -> BBB.txt)
 c) reload
