FTOS Configuration Guide for the C-Series - Force10 Networks

To view the rules of a particular ACL configured on a particular interface, use the show ip accounting
access-list ACL-name interface interface command (Figure 226) in EXEC privilege mode.
Figure 226 Command Example: show ip accounting access-list
Force10#show ip accounting access ToOspf interface gig 1/6
Standard IP access list ToOspf
seq 5 deny any
seq 10 deny 10.2.0.0 /16
seq 15 deny 10.3.0.0 /16
seq 20 deny 10.4.0.0 /16
seq 25 deny 10.5.0.0 /16
seq 30 deny 10.6.0.0 /16
seq 35 deny 10.7.0.0 /16
seq 40 deny 10.8.0.0 /16
seq 45 deny 10.9.0.0 /16
seq 50 deny 10.10.0.0 /16

Figure 227 illustrates how the seq command orders the filters according to the sequence number assigned.
In the example, filter 25 was configured before filter 15, but the show config command displays the
filters in the correct order.
Figure 227 Command example: seq
Force10(config-std-nacl)#seq 25 deny ip host 10.5.0.0 any log
Force10(config-std-nacl)#seq 15 permit tcp 10.3.0.0 /16 any
Force10(config-std-nacl)#show config
!
ip access-list standard dilling
seq 15 permit tcp 10.3.0.0/16 any
seq 25 deny ip host 10.5.0.0 any log
Force10(config-std-nacl)#
To delete a filter, use the no seq sequence-number command in the IP ACCESS LIST mode.
If you are creating a standard ACL with only one or two filters, you can let FTOS assign a sequence
number based on the order in which the filters are configured. The software assigns filters in multiples of 5.
To configure a filter without a specified sequence number, use these commands in the following sequence,
starting in the CONFIGURATION mode:
Step Command Syntax Command Mode Purpose
1 ip access-list standard
access-list-name
2 {deny | permit} {source [mask] |
any | host ip-address} [count
[byte] | log ] [order] [monitor]
CONFIGURATION Create a standard IP ACL and assign it a
unique name.
CONFIG-STD-NACL Configure a drop or forward IP ACL filter.
• log and monitor options are
supported on E-Series only.
When you use the ‘log’ option, CP processor logs details about the packets that match. Depending on how
many packets match the ‘log’ entry and at what rate, the CP may become busy as it has to log these
packets’ details.
