Information
The monitor option is relevant in the context of the flow-based monitoring feature
only. Refer to the Port Monitoring chapter.
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.
The
order option is relevant in the context of the Policy QoS feature only. The
following applies:
•The
seq sequence-number is applicable only in an ACL group.
•The
order option works across ACL groups that have been applied on an interface
via QoS policy framework.
•The
order option takes precedence over the seq sequence-number.
• If
sequence-number is not configured, then rules with the same order value are
ordered according to their configuration order.
• If the
sequence-number is configured, then the sequence-number is used as a tie
breaker for rules with the same order.
You cannot include IP, TCP or UDP (Layer 3) filters in an ACL configured with ARP
or Ether-type (Layer 2) filters. Apply Layer 2 ACLs to interfaces in Layer 2 mode.
seq ether-type
e
Configure an egress filter with a specific sequence number that filters traffic with
specified types of Ethernet packets. This command is supported only on 12-port GE
line cards with SFP optics; refer to your line card documentation for specifications.
Syntax
seq sequence-number {deny | permit} ether-type protocol-type-number
{
destination-mac-address mac-address-mask | any} vlan vlan-id {source-mac-address
mac-address-mask
| any} [count [byte] | log] [order] [monitor]
Parameters
Version 8.2.1.0 Allows ACL control of fragmented packets for IP (Layer 3) ACLs.
Version 8.1.1.0 Introduced on E-Series ExaScale
Version 7.4.1.0 Added
monitor option
Version 6.5.10 Expanded to include the optional QoS
order priority for the ACL entry.
Note: When ACL logging and byte counters are configured simultaneously, byte
counters may display an incorrect value. Configure packet counters with logging
instead.
sequence-number Enter a number from 0 to 4294967290.
deny Enter the keyword deny to drop all traffic meeting the filter criteria.
