Example of Creating a Filter with Dell Networking OS-Assigned Sequence Numbers
The example shows a prefix list in which the software assigned the sequence numbers. The filters were
assigned sequence numbers based on the order in which they were configured (for example, the first
filter was given the lowest sequence number). The show config command in PREFIX LIST mode
displays the two filters with the sequence numbers 5 and 10.
Dell(conf-nprefixl)#permit 123.23.0.0 /16
Dell(conf-nprefixl)#deny 133.24.56.0 /8
Dell(conf-nprefixl)#show conf
!
ip prefix-list awe
seq 5 permit 123.23.0.0/16
seq 10 deny 133.0.0.0/8
Dell(conf-nprefixl)#
To delete a filter, enter the show config command in PREFIX LIST mode and locate the sequence
number of the filter you want to delete, then use the
no seq sequence-number command in PREFIX
LIST mode.
