154 IBM 9077 SP Switch Router: Get Connected to the SP Switch
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.
