Draft Level—Hitachi Confidential

HiSpeed Switch Troubleshooting Guide

❒For AppleTalk users, must be running software version 1.3.28 or later.

❒FDDI Port service can only be bounded to VLAN 1. RIP must be ‘active’ to route traffic from one VLAN to another across FDDI.

❒The FDDI driver execution requires five to six seconds longer than the ATM Uplink driver. This is considered normal operation. The initial installation of the FDDI Uplink will delay the login prompt for approximately 30 seconds while the configuration file is updated.

Caution: It is important not to interrupt the boot up sequence during this

!process by either pressing the front panel Reset switch, or cycling power.

Note: If the HiSpeed Switch is reset by one of these methods during either of the configuration file updates (or even possibly during the driver execution), the FLASH may become corrupted and the switch will subsequently not boot. A FLASH format and Zap of the firmware will be required to recover.

Troubleshooting FDDI:

Problem: The HiSpeed switch is only forwarding broadcast and multicast traffic but not unicast traffic to an Ethernet device directly attached to the HiSpeed switch.

Solution: Use the following solutions:

￿Verify that physical port 34 is active using vvp.

￿If the bridge mode is set to Forwarding, verify that the MAC address of the targeted Ethernet device has been learned in the FDDI Forwarding table. This means that either the Ethernet device has to initiate the connection to the switch or reply to an ARP request.
