Configure an IP ACE

Configure an IP ACE to filter on the source IP address, destination IP address, DiffServ Code Point (DSCP), protocol, IP options, IP fragmentation, and routed packets only.

Before you begin

The ACL exists.
The ACE exists.

About this task

The eq and mask parameters specify an operator for a field match condition: equal to or mask. The mask operator is an implied eq on the mask bits.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Configure an ACE for the DSCP attribute:

filter acl ace ip <1-2048> <1-2000> dscp eq {<0..63>|<0x00..0x3f>|phbcs0|phbcs1|phbaf11|phbaf12|phbaf13|phbcs2|phbaf21|phbaf22|phbaf23|phbcs3|phbaf31|phbaf32|phbaf33|phbcs4|phbaf41|phbaf42|phbaf43|phbcs5|phbef|phbcs6|phbcs7}

OR

filter acl ace ip <1-2048> <1-2000> dscp mask {<0..63>|<0x00..0x3f>|phbcs0|phbcs1|phbaf11|phbaf12|phbaf13|phbcs2|phbaf21|phbaf22|phbaf23|phbcs3|phbaf31|phbaf32|phbaf33|phbcs4|phbaf41|phbaf42|phbaf43|phbcs5|phbef|phbcs6|phbcs7} WORD<0x0-0x40>
Configure an ACE for the destination or source IP address attribute:

filter acl ace ip <1-2048> <1-2000> <dst-ip|src-ip> eq WORD<1–1024>

OR

filter acl ace ip <1-2048> <1-2000> <dst-ip|src-ip> mask WORD<1–1024> {<0–32>|null|<A.B.C.D>}
Configure an ACE for the IP fragmentation attribute:

filter acl ace ip <1-2048> <1-2000> ip-frag-flag eq <noFragment|anyFragment>
Configure an ACE for the IP options attribute:

filter acl ace ip <1-2048> <1-2000> ip-options any
Configure an ACE for the protocol type attribute:

filter acl ace ip <1-2048> <1-2000> ip-protocol-type eq WORD<1–256>
Configure an ACE for routed packets only:

filter acl ace ip <1-2048> <1-2000> routed-only
Ensure the configuration is correct:

show filter acl ip <1-2048> <1-2000>
Optional: Delete all the attributes from the IP (Layer 3) portion of the ACE:

default filter acl ace ip <1-2048> <1-2000>

Example

Switch:1(config)#filter acl ace ip 1 12 dst-ip eq 198.51.100.0

Variable definitions
