CrossFire 8650/8651 UEM Guide to Operation, DOC-7090 v. 1.0

3. Console Configuration

MTU

Sets the maximum frame size for the virtual port, possible values are 1500, 4472, 
8144, 17800, and Use BRF. These values correspond to the standard values used 
on the ordinary Token-Ring ports. Actually, slightly larger frame sizes are allowed 
to accommodate the frame sizes defined by the ATM Forum LAN Emulation 
standard and implemented by the CrossFire 8320/8321 ATM Uplink. Also, the 
IEEE 802.1Q frame tag adds another 10 bytes to each frame.

Table 5 shows the configured and actual frame size, as well as the corresponding 
Largest Frame Size bits that are used in explorer RIF expansion:

Also shown is the actual MTU for the BRF. If Use BRF is selected, the BRF value 
will be used. Otherwise, the lowest of the BRF MTU and port MTU values will be 
used. Thus, a port will never have a higher MTU than its BRF.

Range: 

1500, 4472, 8144, 17800, 

and

 Use BRF

Default: 

Use BRF

.

Forwarding

The virtual port is up and 
forwarding.

Temporary down

The virtual port is currently down 
because the port is temporary 
down.

Ring Number Failure

The virtual port has been auto 
disabled because the virtual port 
has learned a mismatching ring 
number.
