# Configuring PADS Packet Content

By default, an E Series router acting as an AC sends both the AC-Name and AC-Cookie tags as part of the PADS packet when it confirms a session with a PPPoE client. These tags are defined in RFC 2516 as follows:

- AC-Name—String that uniquely identifies the particular AC
- AC-Cookie—Tag used by the AC to help protect against denial of service (DoS) attacks

If necessary for compatibility with your network equipment, you can issue the pppoe pads disable-ac-info command to prevent the router from sending the AC-Name and AC-Cookie tags in the PADS packet.

pppoe pads disable-ac-info

- Use to prevent the router from sending the AC-Name and AC-Cookie tags in the PADS packet.
- The pppoe pads disable-ac-info command affects PADS packets sent only on PPPoE interfaces configured on the router after the command is issued. It has no effect on PADS packets sent on previously created PPPoE interfaces.
- Example
  host1(config)#pppoe pads disable-ac-info
- Use the no version to restore the default behavior, which is to send the AC-Name and AC-Cookie tags in the PADS packet.
- See pppoe pads disable-ac-info.
