For example, to assign a default gateway of 9.67.46.238 to the
token_ring_10 segment on the ShuntBus, you must use the following
command:
8260A> set ip default_gateway 9.67.46.238 token_ring_10
Note that DMM will use the IP address assigned to a segment to
communicate through that segment. Therefore, if you have assigned IP
addresses to more than one backplane segment, your DMM, effectively, has
multiple addresses (one in each segment).
You can display the IP parameters which are currently assigned in your 8260,
using the following command:
8260A> show ip
An example of the output from this command is shown in Figure 29.
8260A> show ip

Figure 29. Output from Show IP Command
In this example, our DMM is assigned three IP addresses:
•
9.67.46.1 for slip connection through the console/auxiliary port
•
9.67.46.46 for connection through Ethernet_1
•
9.67.46.238 for connection through token_ring_10
You can clear any of the IP entries assigned to DMM using the following
command:
8260A> clear ip index
Where
index
is the number of the network shown in Figure 29.
2. When there are multiple default gateways defined, you may select one
gateway, known as the active default gateway, that will be used by DMM to
send the packets to unknown destinations. You can use the following
command to select the active default gateway:
8260A> set ip active_default_gateway 9.67.46.238
If you do not select the active default gateway, by default, the active default
gateway is the default gateway assigned to the first interface that you have
assigned to your DMM. For example, for the DMM shown in Figure 29, the
active default gateway would have been 9.67.46.46 had we not defined
9.67.46.238 as the active default gateway.
