Inserting remarks and related ACEs within an existing list

To insert an ACE with a remark within an ACL by specifying a sequence number:

Procedure
  1. Insert the numbered remark first
  2. Then, using the same sequence number, insert the ACE. 

Switch(config–ipv6–acl)# 15 remark "PERMIT HTTP; STATION 23; SUBNET 1D"
Switch(config–ipv6–acl)# 15 permit tcp host 2001:db8:0:1d::23 eq 80 2001:db8:0:2f::/64


Switch(config–ipv6–acl)# show access config
. . .

ipv6 access-list "List–105"
    10 permit tcp 2001:db8:0:1f::/64 eq 80 2001:db8:0:2f::/64
    15 remark "PERMIT HTTP; STATION 23; SUBNET 1D"
    15 permit tcp 2001:db8:0:1d::23/128 eq 80 2001:db8:0:2f::/64
    20 deny tcp 2001:db8:0:1d::/64 eq 80 2001:db8:0:2f::/64
  exit
. . .
The above two commands insert a remark with its corresponding ACE (same sequence number) between two previously configured ACEs
