I can't get a 3600 and a 7500 w/ ATM DS3 ints to communicate over the PVC through the LS1010!
All documented configuration I've found is v. simple and straightforward, but something is amiss. Any pointers, advice from the groupstudy guys would be great (Note, I have a TAC case open on this and they haven't been able to solve it yet): Here's a diagram of what we have set up. Very simple setup we have: maingw7500 - LS1010 - 3600 atm5/1/0.40 --- atm0/0/0 | atm0/0/1 --------atm1/0 pvc3/40 ------------ pvc 3/40 pvc3/50 ----------pvc3/50 Now for the interface configs on the routers and the entire config of the LS1010: VGW7500 (IOS Version 12.0(9)S) interface ATM5/1/0 no ip address no ip directed-broadcast ip route-cache flow no ip route-cache cef no ip route-cache distributed atm uni-version 3.1 no atm auto-configuration atm ilmi-keepalive no atm address-registration atm ilmi-pvc-discovery ! interface ATM5/1/0.40 point-to-point ip address 150.240.45.1 255.255.255.252 no ip directed-broadcast pvc 3/40 protocol ip 150.240.45.2 no ilmi manage oam-pvc 0 ****NOTE**** here oam-pvc manage brings down the interface! encapsulation aal5snap ----------------------------------------------- Loaner3600 (IOS Version 12.1(5)T5) interface ATM1/0 no ip address ip route-cache flow atm uni-version 3.1 no atm auto-configuration atm ilmi-keepalive no atm address-registration atm ilmi-pvc-discovery ! interface ATM1/0.50 point-to-point ip address 150.240.45.2 255.255.255.252 pvc 3/50 protocol ip 150.240.45.1 oam-pvc manage encapsulation aal5snap ------------------------------------------------- SW1010_Lightstream(IOS Version 12.1(7a)EY3) Current configuration : 1589 bytes ! version 12.1 no service pad service timestamps debug uptime service timestamps log uptime service password-encryption ! hostname sw1010 ! enable secret 5 xxx ! network-clock-select 1 System clock sdm ipqos zero sdm policy 0 ip subnet-zero no ip finger ! ! atm address 47.0091.8100.0000.0009.b71c.3e01.0009.b71c.3e01.00 atm router pnni no aesa embedded-number left-justified node 1 level 56 lowest redistribute atm-static ! ! ! ! interface ATM0/0/0 no ip address no atm auto-configuration no atm address-registration ! interface ATM0/0/1 no ip address no atm auto-configuration no atm address-registration atm pvc 3 50 interface ATM0/0/0 3 40 ! interface ATM0/0/2 no ip address no ip route-cache cef shutdown no atm auto-configuration no atm address-registration atm uni version 3.1 ! interface ATM0/0/3 no ip address shutdown ! interface ATM0 no ip address atm oam interface ATM0/0/0 0 16 seg-loopback rdi atm oam interface ATM0/0/1 0 16 seg-loopback rdi atm oam interface ATM0/0/2 0 16 seg-loopback rdi atm oam interface ATM0/0/3 0 16 seg-loopback rdi atm oam interface ATM0/0/0 0 5 seg-loopback rdi atm oam interface ATM0/0/1 0 5 seg-loopback rdi atm oam interface ATM0/0/2 0 5 seg-loopback rdi atm oam interface ATM0/0/3 0 5 seg-loopback rdi ! interface Ethernet0 ip address 150.240.150.154 255.255.255.0 ! ip classless ip route 0.0.0.0 0.0.0.0 Ethernet0 no ip http server ! ! ! line con 0 transport input none line aux 0 line vty 0 4 exec-timeout 120 0 password 7 xxx login ! end -------------------------------- NOTES: - When the routers are terminated with a physical loopback they ping their own ATM ints just fine. - All interfaces on the routers have been in production in recent past. - SW1010 can terminate its interfaces w/ physical loopback and it looks fine - 3600 interface stopped flapping when we extended its cable. - Routers can ping their own ATM ints also when they are plugged into LS1010 AND the other LS1010 interface it is mapped to is plugged into itself with at physical loopback. - 3600 can ping its own ATM int even when it is plugged into LS1010 AND 7500 is plugged into other LS1010 interface to which its mapped - Also, on the LS1010, when we do a "ping atm interface atm0/0/1 3 50 end-loopback" command it works fine (this is with a normal setup like i just mentioned above), but the same "ping atm" command mapping to the 7500's interface and pvc does not work because we can't run OAM-PVC MANAGE on the 7500 sub-int without it bringing down the interface?? - Throughout this process we have occasionally been able to get pings through from the 3600 atm int to the 7500 atm int. - We've tried many debugs, and one common debug message on pings is "encapsulation failed", but we have aal5snap defined on both ends of the PVC - I know we don't need ILMI on a PVC, but it helps for debugging - Both atm interfaces on the routers are set to CLOCKING=LINE, and the LS1010 is set to "Current clock source:System clock, priority:1" Any advice or help would be appreciated!
