Scenarios

A switch fragments packets in the following scenarios:

  • Jumbo is enabled between an authenticator switch and a client, and jumbo is not enabled between a RADIUS server and an authenticator switch: If the client certificate size is more than the maximum allowed EAP data in RADIUS packet, the switch fragments the packet before forwarding it to the RADIUS server.

  • Jumbo is not enabled between an authenticator switch and a client, and jumbo is enabled between a RADIUS server and an authenticator switch: If the RADIUS server certificate size is more than a standard MTU size, the client cannot receive certificate because of MTU size restriction. The switch fragments the packet before sending it to client.

  • Jumbo is enabled on an authenticator switch and a client, and jumbo is enabled on a RADIUS server and an authenticator switch: If the client certificate size is more than the maximum allowed EAP data in RADIUS packet, then the switch cannot forward packet to the RADIUS server. the Switch fragments packet before sending to a RADIUS server.
