Troubleshooting Bandwidth Oversubscription

Managing Flash Cards on SRP Modules

Use to display the bandwidth oversubscription status for an ERX7xx model or ERX1410
router.
Example 1: This example shows the display when bandwidth oversubscription is enabled.
host1#show bandwidth oversubscription
Bandwidth oversubscription is currently in effect.
Example 2: This example shows the display that appears after you issue the no
bandwidth oversubscription command to disable bandwidth oversubscription.
host1#no bandwidth oversubscription
host1#show bandwidth oversubscription
Bandwidth oversubscription is currently in effect.
Bandwidth oversubscription will not be in effect the next time the system
reboots.
Example 3: This example shows the display when bandwidth oversubscription is
disabled.
host1#show bandwidth oversubscription
Bandwidth oversubscription is currently not in effect.
Example 4: This example shows the display that appears after you issue the bandwidth
oversubscription command to enable bandwidth oversubscription.
host1#bandwidth oversubscription
host1#show bandwidth oversubscription
Bandwidth oversubscription is currently not in effect.
Bandwidth oversubscription will be in effect the next time the system
reboots.
See show bandwidth oversubscription.
If you enter a forbidden combination of line modules or exceed the slot group bandwidth
when you have not configured bandwidth oversubscription, you will see an error message.
For example, suppose you originally configure the router for bandwidth oversubscription
and then want to change to full line rate performance. You forget to remove line modules
or disable slots, and enter the no bandwidth oversubscription command. The following
message appears:
host1(config)#no bandwidth oversubscription
% failed : bandwidth over subscribed at slot 0-2
To resolve the problem, remove the unwanted line modules, or disable the slots that
contain those line modules.
Each SRP module contains a flash card that stores system files. On the E120 and E320
routers, each SRP module can have an additional flash card; the second card is reserved
for the storage of core dumps.
