Table 43: Combinations of Line Modules for Line Rate
Performance—SRP-5G+ Module in an ERX705 Router (continued)
Possible Combinations of Line
Modules In Slot Groups
One supported line module
and one empty slot in slot
group 1
NOTE: The SRP-5G+ module
supports all line modules
listed in Table 40 on page 361.
Two OCx/STMx ATM line
modules in slot group 1
One cOCx/STMx, COCX-F3,
CT3/T3 FO, GE/FE, IPSec
Service, or OCx/STMx line
module in slot groups 2, 3, and
4
After you have installed a suitable combination of line modules, you can specify a different
type of performance. To specify the type of performance:
Issue the show bandwidth oversubscription command.
1.
If the setting is not the one you want, enable or disable bandwidth oversubscription.
2.
Reboot the router.
3.
Use to enable bandwidth oversubscription for an ERX7xx model or ERX1410 router.
Reboot the router after you have issued this command to change the bandwidth
oversubscription status.
By default, bandwidth oversubscription is enabled.
Example
host1(config)#bandwidth oversubscription
Use the no version to disable bandwidth oversubscription. Reboot the router after you
have issued this command to change the bandwidth oversubscription status.
See bandwidth oversubscription.
Use the show bandwidth oversubscription and show utilization (see "Monitoring
Modules" on page 394) commands to monitor the status of bandwidth oversubscription.
