# PVC for IP (RFC 1577)

PVC ga030 0/35 proto=llc

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 

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.

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.
