Chapter 6 Configuring PPPoE over Ethernet and IEEE 802.1Q VLAN
Static MAC Address for PPPoE
Note Although the Static MAC Address for PPPoE feature is configurable for VPDN groups, we recommend
that you configure this feature for BBA groups.
The configuration of the Static MAC Address for PPPoE feature for BBA groups and VPDN groups is
mutually exclusive. If you configure a MAC address as a source MAC address for a BBA group, a VPDN
group cannot use this MAC address as a source MAC address for the VPDN group. To apply the BBA
group MAC address to a VPDN group, you must manually configure the Static MAC Address for PPPoE
feature for the VPDN group as well.
Example 6-3 shows how you can throttle PPP sessions using the MAC address. This example allows a
maximum of five sessions from each MAC address. If more than five sessions are attempted from this
MAC address, any sessions using that particular MAC address are throttled for 30 seconds.
Example 6-3 Throttling PPP Sessions Using the MAC Address
bba-group pppoe PPPoE
virtual-template 1
sessions per-vc limit 32000
sessions per-mac limit 32000
sessions per-mac throttle 5 1 30
To get a list of the throttled MAC addresses, use the show pppoe throttled mac command in privileged
EXEC mode:
Router# show pppoe throttled mac
MAC(s) throttled
