{deny|permit}
SFTOS Command Reference for the S2410, Version 2.4.1.0 289
Usage
A rule may either deny or permit traffic according to the specified classification fields. At a
minimum, the source and destination MAC value must be specified, each of which may be
substituted using the keyword
any to indicate a match on any value in that field. The
remaining command parameters are all optional, but the most frequently used parameters
appear in the same relative order as shown in the command format.
The srcmacmask variable uses a wildcard called an inverted mask. In an inverted mask, a zero in a
bit in the mask means “exact match required”. A one in a mask bit means “match anything here”. For
example:
• To deny all traffic from MAC address 00:00:00:00:03:02, the mask is 00:00:00:00:00:00.
• To deny all traffic from 00:00:00:00:03:xx, the mask is 00:00:00:00:00:ff.
The Ethertype (ethertypekey) may be specified as either a keyword or a four-digit
hexadecimal value from 0x0600-0xFFFF. The currently supported
ethertypekey values are:
appletalk, arp, ibmsna, ipv4, ipv6, ipx, mplsmcast, mplsucast, netbios, novell,
pppoe, and rarp. Each of these translates into its equivalent Ethertype value(s), as shown in
Table 23.
secondary-vlan
(Optional) As above, for the vlan keyword.
secondary-cos (Optional) As above, for the cos keyword.
assign-queue (Optional) The assign-queue parameter allows specification of a particular
hardware queue for handling traffic that matches this rule. The allowed
queue-id value is 0-(n-1), where n is the number of user configurable queues
available for the hardware platform. (See the Usage section, below.)
redirect (Optional) The redirect parameter redirects traffic matching this rule to the
specified egress port. The redirected packet carries the same MAC address
as it would have if it had not been redirected (the MAC address of the next
hop defined in the routing table). Basically, it looks like a mirrored packet on
the redirect port. (See the Usage section, below.)
Note: The no form of this command is not supported, as the rules within an ACL group
cannot be deleted individually. Rather, the entire ACL group must be deleted and
re-specified.
