Lexmark IBM 9077 manual Bridging ATM, Configuration for ARP Service grarp.conf

PVC ga030 0/32 proto=vcmux_bridge,ether

PVC ga030 0/33 proto=vcmux_bridge,ether_fcs

PVC ga030 0/34 proto=vcmux_bridge,bpdu

#PVC for IP (RFC 1577) PVC ga030 0/35 proto=llc

Note: IP routed traffic is transmitted on its own PVC. If the separate IP PVC were not defined, then routed IP datagrams would be encapsulated as Ethernet frames.

4.6.11.5 Configuration for ARP Service - grarp.conf

If needed, supply IP-to-physical address mapping information for ARP service.

Put an entry into /etc/grarp.conf only if the remote destination does not support InATMARP, which the GRF does.

A sample entry would be:

#[ifname] host hwaddr [temp] [pub] [trail]

ga020 172.0.130.111 0/32

4.6.11.6 Installing Configuration Changes

When you enter configuration information or make changes, you must do a grwrite command to save the /etc directory to permanent storage. In the CLI, or from the UNIX shell, enter grwrite -v.

You must also reset the media card for the changes to take place. Type

grreset <slot_number>.

Note: We found that grreset would not be enough to get things up correctly, especially if the interfaces were already in use before.

We recommend using grwrite -v,followed by reboot -i.

Do not start hunting for bugs before you have tried these two commands.

4.6.12 Bridging ATM

The information in the previous chapter was used in implementing bridging with two ATM ports between two GRFs; see Section 7.1.2, “ATM OC-3c Backbone - Using Two Ports” on page 215.
