Administration of the Avaya G350 Media Gateway - Avaya Support

Initial WAN configuration4. Configure an authentication method and parameters:- For PAP authenticating, type the ppp pap-sent command, followed by a usernameand password. For example:G350-001(super-if:FastEthernet 10/2)# ppp pap-sent username avaya32 password 123456Done!- For CHAP authentication, use the ppp chap hostname command, followed by ahostname, and the ppp chap password command, followed by a password. Forexample:G350-001(super-if:FastEthernet 10/2)# ppp chap hostname avaya32Done!G350-001(super-if:FastEthernet 10/2)# ppp chap password 123456Done!Note:Note:Authentication parameters do not appear in the startup or running configurationfiles. You can use the show ppp authentication command to viewauthentication status. The copy running-config startup-configcommand stores authentication parameters in NVRAM.5. You can use the following commands to change the interface parameters:- Use the pppoe-client service name {name}command to force the PPPoE clientto connect only to access concentrators that support a specific service name. Use the noform of this command to deactivate connection to a specific service name. Whenconnection to a specific service name is deactivated, the PPPoe client attempts toautomatically discover the service name by initiating PADI frames with a blank servicename.- Use the mtu command to set the interface’s MTU to 1492. Since the header size ofPPPoE packets is 8 bytes, setting the MTU to 1492 ensures that the overall packet sizefor the PPPoE interface will not exceed 1500, which is the MTU for Ethernet.- Use the pppoe-client wait-for-ipcp command to set the amount of time (inseconds) between establishment of the PPPoE tunnel and establishment of the IPCPtunnel. If this time is exceeded, the PPPoE client terminates the PPPoE tunnel.- Use the pppoe-client persistent delay command to set the interval betweenpppoe-client dial attempts.- Use the pppoe-client persistent max-attempts command to limit the numberof consecutive connection establishment retries. When this number is reached, thePPPoE client stops trying to establish connections. To have the PPPoE client resumeIssue 3 January 2005 93
