they have the same number before and after the command is entered. Remark 4 is incremented as a rule, and all rules
have retained their original positions.
Example of Resequencing ACLs When Remarks and Rules Have Different Numbers
FTOS(config-ext-nacl)# show config
!
ip access-list extended test
remark 4 XYZ
remark 5 this remark corresponds to permit any host 1.1.1.1
seq 5 permit ip any host 1.1.1.1
remark 9 ABC
remark 10 this remark corresponds to permit ip any host 1.1.1.2
seq 10 permit ip any host 1.1.1.2
seq 15 permit ip any host 1.1.1.3
seq 20 permit ip any host 1.1.1.4
FTOS# end
FTOS# resequence access-list ipv4 test 2 2
FTOS# show running-config acl
!
ip access-list extended test
remark 2 XYZ
remark 4 this remark corresponds to permit any host 1.1.1.1

remark 6 this remark has no corresponding rule
remark 8 this remark corresponds to permit ip any host 1.1.1.2
seq 8 permit ip any host 1.1.1.2

Route Maps
Route maps are supported on Z9000 platform.
Similar to ACLs and prefix lists, route maps are composed of a series of commands that contain a matching criterion and
an action; however, route maps can change the packets meeting the criterion. ACLs and prefix lists can only drop or
forward the packet or traffic. Route maps process routes for route redistribution. For example, a route map can be called
to filter only specific routes and to add a metric.
Route maps also have an “implicit deny.” Unlike ACLs and prefix lists; however, where the packet or traffic is dropped, in
route maps, if a route does not match any of the route map conditions, the route is not redistributed.
Implementation Information
The FTOS implementation of route maps allows route maps with the no match or no set commands. When there is
no match command, all traffic matches the route map and the set command applies.
Important Points to Remember
• For route-maps with more than one match clause:
– Two or more match clauses within the same route-map sequence have the same match commands
(though the values are different), matching a packet against these clauses is a logical OR operation.
– Two or more match clauses within the same route-map sequence have different match commands,
matching a packet against these clauses is a logical AND operation.
• If no match is found in a route-map sequence, the process moves to the next route-map sequence until a match
is found, or there are no more sequences.
