Ok, after a little guess work, I have it! Routers are RouterB and RouterE Serial 0/1 on both are connected via a T-1 crossover Chap authentication callin on routerB Chap authentication optional on routerE Username is ROUTERB and ROUTERE respectively.
And from router B we have: 2w4d: %LINK-3-UPDOWN: Interface Serial0/1, changed state to up 2w4d: Se0/1 CHAP: Using alternate hostname ROUTERB 2w4d: Se0/1 CHAP: O CHALLENGE id 189 len 28 from "ROUTERB" 2w4d: Se0/1 CHAP: I CHALLENGE id 176 len 28 from "ROUTERE" 2w4d: Se0/1 CHAP: Using alternate hostname ROUTERB 2w4d: Se0/1 CHAP: O RESPONSE id 176 len 28 from "ROUTERB" 2w4d: Se0/1 CHAP: I RESPONSE id 189 len 28 from "ROUTERE" 2w4d: Se0/1 CHAP: O SUCCESS id 189 len 4 2w4d: Se0/1 CHAP: I SUCCESS id 176 len 4 ROUTER_B# Now for Router E we have: 2w4d: Se0/1 CHAP: Using alternate hostname ROUTERE 2w4d: Se0/1 CHAP: O CHALLENGE id 177 len 28 from "ROUTERE" 2w4d: Se0/1 CHAP: I CHALLENGE id 190 len 28 from "ROUTERB" 2w4d: Se0/1 CHAP: Using alternate hostname ROUTERE 2w4d: Se0/1 CHAP: O RESPONSE id 190 len 28 from "ROUTERE" 2w4d: %LINK-3-UPDOWN: Interface Serial0/1, changed state to up 2w4d: Se0/1 CHAP: I RESPONSE id 177 len 28 from "ROUTERB" 2w4d: Se0/1 CHAP: O SUCCESS id 177 len 4 2w4d: Se0/1 CHAP: I SUCCESS id 190 len 4 ROUTER_E# Next up PPP Pap Router B: ( ppp authen pap optional ) 2w4d: %SYS-5-CONFIG_I: Configured from console by console 2w4d: %LINK-3-UPDOWN: Interface Serial0/1, changed state to down 2w4d: Se0/1 PPP: Treating connection as a dedicated line 2w4d: %LINK-3-UPDOWN: Interface Serial0/1, changed state to up 2w4d: Se0/1 PAP: O AUTH-REQ id 2 len 18 from "ROUTERB" 2w4d: Se0/1 PAP: I AUTH-REQ id 2 len 18 from "ROUTERE" 2w4d: Se0/1 PAP: Authenticating peer ROUTERE 2w4d: Se0/1 PAP: O AUTH-ACK id 2 len 5 2w4d: Se0/1 PAP: I AUTH-ACK id 2 len 5 2w4d: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/1, changed state t o up ROUTER_B# Router E: ( ppp authen pap callin ) 2w4d: %LINK-3-UPDOWN: Interface Serial0/1, changed state to up 2w4d: Se0/1 PPP: Treating connection as a dedicated line 2w4d: Se0/1 PAP: O AUTH-REQ id 2 len 18 from "ROUTERE" 2w4d: Se0/1 PAP: I AUTH-REQ id 2 len 18 from "ROUTERB" 2w4d: Se0/1 PAP: Authenticating peer ROUTERB 2w4d: Se0/1 PAP: O AUTH-ACK id 2 len 5 2w4d: Se0/1 PAP: I AUTH-ACK id 2 len 5 2w4d: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/1, changed state t o up ROUTER_E# Thanks Larry -----Original Message----- From: Priscilla Oppenheimer [mailto:[EMAIL PROTECTED]] Sent: Monday, May 20, 2002 6:15 PM To: [EMAIL PROTECTED] Subject: debug ppp authentication [7:44575] Cisco documentation claims that there is a "debug ppp authentication" command. Such a command does not exist on my routers (which are running 11.0). Would anyone be willing to see if it exists on newer routers? Set up two routers connected via a serial link to use PPP encapsulation. Use PAP authentication. Shut down one of the interfaces, enable the debug command, no shut the interface and see what happens! I say to use PAP because I know that the "debug ppp chap" command works. I'm more interested in seeing if you can debug PAP. Thanks!
