Configuring Resources for a VS
Context
Physical resources: Only physical Ethernet interfaces on interface cards can be allocated. By default, all interfaces on an interface card belong to the Admin-VS.
Logical resources: Allocatable logical resources include unicast routing entries, multicast routing entries, VLANs, and other resources. By default, a new VS has the default logical resource specifications. For details, see Default Settings for VSs. You can use a logical resource template to modify specifications of logical resources in batches or modify specifications of a specified resource item for a VS.
Only the PS administrator can allocate physical interfaces to VSs.
Only physical interfaces on interface cards can be assigned to VSs. However, the CSS and Eth-Trunk member interfaces cannot be assigned to VSs. After an interface is allocated to a VS, original configurations on the interface are deleted.
In group mode, all interfaces on the same group must be allocated to the same VS.
There is no mapping between a logical resource template and a VS. After a logical resource template is loaded on a VS, modifying the logical resource template does not affect the VS. The modified logical resource template takes effect only after it is loaded to the VS again.
Procedure
- Assign physical interface resources.
- (Optional) Assign logical resources.
- Set logical resource specifications.
Use a logical resource template to allocate logical resources to the VS.
Run assign resource-template template-name
A logical resource template is loaded on the VS.
A user can run the port-mode group [ resource-template template-name ] command to specify a logical resource template for a VS when configuring the interface assignment mode or run the assign resource-template template-name command to specify a logical resource template for the VS.
Skip this step if a logical resource template has been specified for the VS in the port-mode group [ resource-template template-name ] command.
Set specifications of specified resource items.
Run resource { u4route | m4route | u6route | m6route | vlan | vpn-instance } upper-limit resource-limit
The specifications of the routing entry, VLAN, or VPN instance are set.
Run resource { cpu weight weight | memory ratio-threshold ratio-threshold | disk ratio-threshold disk-ratio-threshold }
The maximum CPU usage, storage space, and memory usage are set.
Run resource mcast enable
Multicast is enabled.
- Set logical resource specifications.
