TCP/IP default Token-Ring values
Valid token-ring network adapter attributes can have their values changed using the Network Interface Selection menu in SMIT.
| Attribute | Default value | Possible values |
|---|---|---|
| netaddr | ||
| netmask | ||
| state | down | up, down, detach |
| arp | yes | yes, no |
| hwloop | no | yes, no |
| netmask | ||
| broadcast | ||
| allcast | no | yes, no |
The following valid token-ring network device driver attributes are shown along with its default values, which can be changed using the Network Interface Drivers menu in SMIT.
| Attribute | Default value | Possible values |
|---|---|---|
| mtu (4Mbps) | 1500 | 60 through 4056 |
| mtu (16Mbps) | 1500 | 60 through 17960 |
Note: When operating through a bridge, the default value of 1500 for
the maximum transmission unit (MTU) should be changed to a value
that is 8 less than the maximum information field (maximum I-frame)
advertised by the bridge in the routing control field. For example,
if the maximum I-frame value is 1500 in the routing control field,
the MTU size should be set to 1492. This is for token-ring network
interfaces only. For more information, see TCP/IP problems with a Token-Ring/Token-Ring bridge.
When using the IBM® 16/4 PowerPC token-ring adapter (ISA), the MTU is restricted to 2000.
