permit ether-type
e
Configure a filter that allows 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
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]
To remove this filter, use one of the following:
• Use the
no seq sequence-number command syntax if you know the filter’s
sequence number or
• Use the
no permit ether-type protocol-type-number {destination-mac-address
mac-address-mask
| any} vlan vlan-id {source-mac-address mac-address-mask | any}
command.
Parameters
protocol-type-number Enter a number from 600 to FFF 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, 1-2094 for ExaScale (can used IDs 1-4094)
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.
