bandwidth

bandwidth

Defines/deletes the bandwidth for a tunnel, default tunnel, or tunnel parameter-set.

Syntax: [no] bandwidth bw

bw

Specifies the bandwidth for the tunnel or parameter set. Bandwidth is specified using one of the following options:

0-4294967295{b} - specifies the number of bits per second assigned as the bandwidth

0.0000-65535.000 {k | m | g} - specifies the number of bits per second assigned as the bandwidth using floating point notation. {k | m | g} specifies kilobits, megabits or gigabits per second.

t1 -       specifies a bandwidth of 1.544 megabits/sec.

t3 -      specifies a bandwidth of 44.736 megabits/sec.

oc3 -    specifies a bandwidth of 155.520 megabits.sec.

oc12 -   specifies a bandwidth of 622.080 megabits/sec.

oc48 - specifies a bandwidth of 2488.320 megabits/sec.

oc192 - specifies a bandwidth of 9953.280 megabits/sec.

Description: Bandwidth refers to the number of bits per second that can be routed through a tunnel. SONET includes substantial overhead information, allowing simpler multiplexing and greatly expanded operations, administration, maintenance, and provisioning capabilities. This overhead information consumes a portion of the total bandwidth that is not available for routing traffic. The following table lists the total transmission rate and associated available bandwidths for four OC speeds:

Table 1-1. Transmission Rate and Associated Bandwidth for Specified OC Speeds
OC Designation Transmission Rate Available Bandwidth

OC-3c

155.520 Mb/sec.

150 Mb/sec.

OC-12c

622.080 Mb/sec.

601.34 Mb/sec.

OC-48c

2488.320 Mb/sec.

2405.38 Mb/sec.

OC-192c

9953.280 Mb/sec.

9621.5 Mb/sec.

Use the bandwidth command to define the bandwidth for a tunnel, default tunnel, or a tunnel parameter-set.

Use the no bandwidth command to delete a bandwidth definition for a tunnel, default tunnel or tunnel parameter-set.

Factory Default: 0.

Command Mode: Traffic engineering parameter-set and traffic engineering tunnel-name.

Example: In the following example:

The tunnel name command changes the command mode to traffic engineering tunnel-name.

The bandwidth command sets the bandwidth reservation for this tunnel to OC12 (622 megabits per second).

The show mpls te tunnel command displays the new setting:

router#config terminal

Enter configuration commands, one per line. End with CNTL/Z.

router(config)#mpls te ospf

router(config-te)#tunnel oc12toBos

router(config-te-tunnel)# bandwidth oc12

router(config)#end

router#show mpls te tunnel

bw	Specifies the bandwidth for the tunnel or parameter set. Bandwidth is specified using one of the following options: 0-4294967295{b} - specifies the number of bits per second assigned as the bandwidth 0.0000-65535.000 {k \| m \| g} - specifies the number of bits per second assigned as the bandwidth using floating point notation. {k \| m \| g} specifies kilobits, megabits or gigabits per second. t1 - specifies a bandwidth of 1.544 megabits/sec. t3 - specifies a bandwidth of 44.736 megabits/sec. oc3 - specifies a bandwidth of 155.520 megabits.sec. oc12 - specifies a bandwidth of 622.080 megabits/sec. oc48 - specifies a bandwidth of 2488.320 megabits/sec. oc192 - specifies a bandwidth of 9953.280 megabits/sec.
