Configuration of IP-Forwarding Media Cards 131
This completes the procedure to configure FDDI cards, and as with the ATM
card, we would like to introduce some of the maint commands we found to be
useful.
4.4.9 Some maint Commands for the FDDI Media Card
The maint commands display a range of information about the FDDI media
card. The FDDI card has an individual processor for the transmit and receive
side, and two sets of maint commands. One set, the maint 1 commands,
covers the receive (RX) side, while the second set, the maint 70 commands,
covers the transmit (TX) side.
To use maint, follow these steps:
• First, switch to the maint prompt with the grrmb command. A new prompt,
GR 66>, will appear.
• Then change the prompt port to the FDDI media card you are working
with. For example, if you are working with a card in slot 0, enter port 0 at
the GR> 66 prompt.
The following message is returned along with the changed prompt:
Current port card is 0
GR 0>
• To leave any maint prompt and return to the shell, enter quit.
Following are just a few maint commands we have found useful; of course,
your needs may vary.
To obtain a list of FDDI CPU0 maint commands, enter maint 1. Enter the
maint 70 command to switch to the set of CPU1 commands. The maint 3
command returns configuration information for each interface; to list statistics
per FDDI interface, use maint 4; to list switch interface statistics, enter
maint 5.
Clear all statistics with the maint 7 command. Display the current ARP table’s
content with maint 70 8. Reset individual FDDI interfaces using maint 12 and
the physical interface number (0–3); maint 12 0 will reset port 0.
