IPv4 Access Control Lists (ACLs)
Editing an Existing ACL
Inserting Remarks and Related ACEs Within an Existing List. To
insert an ACE with a remark within an ACL by specifying a sequence number,
insert the numbered remark first, then, using the same sequence number,
insert the ACE. (This operation applies only to ACLs accessed using the
“Named-ACL” (nacl) context.) For example:
ProCurve(config-std-nacl)# 15 remark "HOST 10.10.10.21"
Inserting a remark/ACE pair with
ProCurve(config-std-nacl)# 15 permit host 10.10.10.21
the same sequence number
requires that the remark (with
ProCurve(config-std-nacl)# show run
the desired sequence number)
ip access-list standard "My-List"
be inserted before the ACE with
10 permit 10.10.10.15 0.0.0.0
the same number.
15 remark "HOST 10.10.10.21"
15 permit 10.10.10.21 0.0.0.0
20 deny 10.10.10.1 0.0.0.255
30 remark "HOST-10.20.10.34"
30 permit 10.20.10.34 0.0.0.0
exit
Figure 9-24. Example of Inserting a Remark
Inserting a Remark for an ACE that Already Exists in an ACL. If a
sequence number is already assigned to an ACE in a list, you cannot insert a
remark by assigning it to the same number. (To configure a remark with the
same number as a given ACE, the remark must be configured first.) To assign
a remark to the same number as an existing ACE:
1. Delete the ACE.
2. Configure the remark with the number you want assigned to the pair.
3. Re-Enter the deleted ACE with the number used to enter the remark.
Removing a Remark from an Existing ACE. If you want to remove a
remark, but want to retain the ACE, do the following:
1. Use the Named ACL context to enter the ACL.
2. Using show run or show access-list < list-name >, note the sequence number
and content of the ACE having a remark you want to remove.
3. Delete the ACE.
4. Using the same sequence number, re-enter the ACE.
