4.2.9 Using grstat to Display GRF Statistics

Use the

grstat -w70 all <interface>

command to display the current statistics

of the ATM OC-3c card’s IP stack. The following is an actual screen shot:

# grstat -w70 all ga010

4.3 ATM OC-12c Configuration

This section provides information needed to configure the ATM OC-12c
media card. The GRF can be configured in point-to-point or
point-to-multipoint ATM topologies with either switches or hosts.

The ATM OC-12c card is very similar to the OC-3c card introduced in Section
4.2, “ATM OC-3c Configuration” on page 110,
so only the differences between
the two cards will be handled here.

The OC-12c media card provides one physical ATM interface, which supports
220 logical interfaces and operates at 622Mbit/s full duplex.

4.3.1 Physical and Logical ATM Interfaces

Figure 40 on page 120 shows the organization of physical and logical ATM
interfaces on the ATM OC-12c media card.
