246 | Access Control Lists (ACL)

• 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
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.
permit
Enter the keyword
permit
to forward all traffic meeting the filter criteria.
protocol-type-number
Enter a number from 600 to FFFF as the specific Ethernet type traffic to drop.
destination-mac-address
mac-address-mask
Enter a MAC address and mask in the nn:nn:nn:nn:nn format.
For the MAC address mask, specify which bits in the MAC address must
match.
The MAC ACL supports an inverse mask, therefore, a mask of ff:ff:ff:ff:ff:ff
allows entries that do not match and a mask of 00:00:00:00:00:00 only allows
entries that match exactly.
any
Enter the keyword
any
to match and drop specific Ethernet traffic on the
interface.
vlan vlan-id
Enter the keyword
vlan
followed by the VLAN ID to filter traffic associated
with a specific VLAN.
Range: 1 to 4094, 1 to 2094 for ExaScale (can used IDs 1 to 4094)
To filter all VLAN traffic specify VLAN 1.
source-mac-address
mac-address-mask
Enter a MAC address and mask in the nn:nn:nn:nn:nn format.
For the MAC address mask, specify which bits in the MAC address must
match.
The MAC ACL supports an inverse mask, therefore, a mask of ff:ff:ff:ff:ff:ff
allows entries that do not match and a mask of 00:00:00:00:00:00 only allows
entries that match exactly.
count
(OPTIONAL) Enter the keyword
count
to count packets processed by the
filter.
byte
(OPTIONAL) Enter the keyword
byte
to count bytes processed by the filter.
log
(OPTIONAL, E-Series only) Enter the keyword
log
to have the information
kept in an ACL log file.
