Token Ring Interfaces
To configure a Token Ring interface
1. Click Interfaces under Configuration > Interface Configuration in the tree view.
2. Click the physical interface link to configure in the Physical column.
Example:
tok-s3p1
The physical interface setup page appears.
3. In the Ring Speed column of the Physical configuration table, select the desired value: 16
Mbit/sec or 4 Mbit/sec.
There is no default value.
4. In the MTU field, enter the desired value.
The minimum for both ring speeds is 560. The maximum MTU for 4 Mbs is 4442, and the
maximum MTU for 16 Mbs is 17792.
5. In the Allow Source routes (Multi-Ring) field, select On or Off.
Default is On. This feature specifies whether or not to support source routes.
6. In the Select Use Broadcast instead of Multicast field, select On or Off.
Default is Off. This option specifies the mapping of an IP multicast address. When the
option is on, it maps a multicast address to an all-ring broadcast address:
[
ff:ff:ff:ff:ff:ff]. When the option is off, it maps a multicast IP address to an IEEE-
assigned IP multicast group address: [noncanonical form:
c0:00:00:04:00:00].
7. Click the logical interface name in the Interface column of the Logical interfaces table to go
to the Interface page.
8. In the Active column of the Logical interfaces table, select On or Off.
Default is On. This setting enables or disables the logical interface. Use this switch to
control access to the network or virtual circuit that corresponds to the logical interface.
9. Click Apply.
Click Up to return to the interface configuration page.
10. Click the logical interface link to configure in the Logical column.
Example: tok-s3p1c0
The logical interface setup page appears.
11. Enter the IP address for the device in the New IP address text box.
12. Enter the IP subnet mask length in the New Mask Length text box.
Click Apply.
Each time you click Apply, the configured IP address and mask length are added to the table.
The entry fields remain blank to allow you to add more IP addresses.
