Front-end bandwidth

Front-end port bandwidth allocation is calculated as follows:

• Each 10 GbE port is allocated 10 Gbps of front-end bandwidth. The total front-end port

bandwidth allocation cannot exceed 10 Gbps per 10 GbE port.

• The total front-end port bandwidth allocation is calculated by adding up the consumed

bandwidth for each FCIP tunnel using that XGE port.

• The consumed bandwidth for a given FCIP tunnel is calculated by adding up the maximum

committed rates (not rounded) for all metric 0 circuits using that XGE port, adding up the

maximum rates (not rounded) for all metric 1 circuits using that XGE port, then taking the

greater of the two values.

Crossports

Crossports are addresses and routes that belong to the other 10GbE (XGE) port’s DP or VE group.

The crossport for xge0 is xge1 and for xge1, the crossport is xge0. To use crossports, the port must

be configured in 10 Gbps mode.

NOTE

XGE and GbE port may be used interchangeably in this document.

You can configure IP addresses on crossports, configure a circuit with metrics for circuit failover on

crossports, and configure VE_Ports that are normally available on the a local XGE port to operate

through a crossport. The crossport is the non-local XGE port for a VE_Port group. In other words, for

VE ports 12 through 21, xge1 is the local XGE port and xge0 is the crossport. For VE ports 22

through 31, xge0 is the local XGE port and xge1 is the crossport.

Configuring crossports

Configure crossport XGE port addresses using the --crossport or -x (shorthand) options for the

portcfg ipif command, as shown in the following example. Note that in this example, IP address

192.168.11.20, created for a FX8-24 blade in slot 8 on port xge0 will be available for circuits on VE

ports 12 through 21.

portcfg ipif 8/xge0 create 192.168.11.20 255.255.255.0 1500 --crossport

portcfg ipif 8/xge0 create 192.168.11.20 255.255.255.0 1500 –x

Delete the crossport address using the delete option instead of the create option for the portcfg ipif

command.

portcfg ipif 8/xge0 delete 192.168.11.20 255.255.255.0 1500 –x
