An example is shown next.

• Assigns a metric value of 2 to the static route.
• Assigns the name “route1” to the static route.
33.7 Enabling MAC Filtering
You can create a filter to drop packets based on the MAC address of the source or the
destination.
Syntax:
mac-filter name <name> mac <mac-addr> vlan <vlan-id> drop <src/dst/both>
where
[metric <metric>]
= The metric represents the “cost” of transmission for routing
purposes. IP routing uses hop count as the measurement of
cost, with a minimum of 1 for directly connected networks.
Enter a number that approximates the cost for this link. The
number need not be precise, but it must be between 1 and
15. In practice, 2 or 3 is usually a good number.
[name <name>]
= Specifies a descriptive name (up to 32 printable ASCII
characters) for identification purposes.
[inactive]
= Deactivates a static route
sysname(config)# ip route 172.21.1.104 255.255.0.0 192.168.1.2
sysname(config)# ip route 172.21.1.104 255.255.0.0 192.168.1.2 metric 2
sysname(config)# ip route 172.21.1.104 255.255.0.0 192.168.1.2 name route1
name <name>
= Names the filtering rule.
mac <mac-addr>
= Specifies the MAC address you want to filter.
