assign resource-mode

Function

The assign resource-mode command configures the resource allocation mode of the device.

The undo assign resource-mode command restores the default resource allocation mode of the device.

By default, the resource allocation mode of the S5720-EI is enhanced-mac and that of the S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S5731-S, S5731S-S, S6730-S, S6730S-S, S6730-H, S6730S-H, S6720-HI, S6720-EI, and S6720S-EI is enhanced-arp.

Usage Guidelines

Usage Scenario

If a device's MAC address entries, FIB entries, or ARP entries are insufficient to meet service requirements, you can use this command to change the resource allocation mode so as to extend the entry space.

On the S5720-HI, when the resource allocation mode is set to eca, the specifications of MAC, FIB, ARP, ND, and multicast entries will not be modified, and only the counter specifications of ACL resources will decrease from 65536 (64K) to 49152 (48K). To view the counter specifications of ACL resources, run the display acl resource command.

On the S5730-HI, S5731-H, S5731S-H, S5731-S, S5731S-S, when the resource allocation mode is set to eca or sac, the specifications of MAC, FIB, ARP, ND, and multicast entries will not be modified. For the S5730-HI, S5731-H, S5731S-H, S5731-S, S5731S-S, when the resource allocation mode is set to sac, NetStream aggregation flows will not be supported.

On the S6730-S and S6730S-S, when the resource allocation mode is set to sac, the specifications of MAC, FIB, ARP, ND, and multicast entries will not be modified.

On the S6720-HI, when the resource allocation mode is set to eca, the specifications of MAC, FIB, ARP, ND, and multicast entries will be modified, and the counter specifications of ACL resources will decrease from 65536 (64K) to 49152 (48K). To view the counter specifications of ACL resources, run the display acl resource command.

Precautions

The configured resource allocation mode takes effect only after the device is restarted. To view the resource allocation modes that take effect currently and take effect after the device restarts, run the display resource-mode configuration command.
The requirements for different entry spaces will change when service configuration is adjusted. In this case, you can change the resource allocation mode to meet the new service requirements. Subsequently, entry spaces in different resource allocation modes will change. Therefore, before changing the resource allocation mode, consider the benefit and loss that the new mode will bring.
In versions earlier than V200R012C00, the resource allocation mode used by the device is recorded in only the flash memory but not the configuration file. In V200R012C00 and later versions, the resource allocation mode used by the device is recorded in both the flash memory and configuration file. If the resource allocation mode used by the device is not the default mode, and the save command is executed to save the configuration after the device is upgraded to V200R012C00 or later, the corresponding configuration is added to the configuration file.

When the resource allocation mode of the following models is changed, the specifications of MAC, FIB, ARP, ND, or multicast entries will be modified.

On the S6720-EI and S6720S-EI, MPLS and Layer 3 VXLAN Gateway are not supported in super-arp resource allocation mode.
