Hitachi US7070447-001 ATM/SHOW cip cip id /VLAN/SHOW/router, ATM/SHOW cip cip id /VLAN/SHOW/vlan

Draft Level—Hitachi Confidential

Basic ATM Concepts

Problem: The CIP connection is up and active but I cannot ping across the ATM network.

Solution: Use the following solutions:

￿Verify that all IP addresses, subnet masks, and gateways are set correctly on the VLANs and any attached devices

￿Verify the same subnet mask is being applied to the CIP and VLAN interfaces.

/ATM/SHOW >cip <cip id> /VLAN/SHOW/router

￿Verify any of the CIP IP addresses must be on a different IP subnet than those VLANs existing on the HiSpeed switches.

/ATM/SHOW >cip <cip id> /VLAN/SHOW/vlan

￿Verify the VLANs communicating with one another over ATM belong to different IP subnets. VLANs belonging to the same IP subnet are not allowed to communicate with one another via CIP.

/VLAN/SHOW/VLAN

￿If using PVC, verify the VCI values are identical on the HiSpeed switches. However, the CIP index does not need to be the same on both switches.

/ATM/SHOW >cip

￿Verify that RIP is active for CIP and verify all routes are being learned.

/ATM/SHOW >cip <cip id> /INET/SHOW >route
