Configuring the Resource Mode of the Extended Entry Space
Context
A device maintains many MAC address entries, FIB entries, and ARP entries when processing a large number of services. However, the number of the entries supported by the device is limited. If these entries cannot meet service requirements, the service processing efficiency degrades. A device provides the function that extends entry spaces and allows configuring the resource mode of the extended entry space to extend the MAC address, FIB entry, or ARP entry spaces as required.
Procedure
- (Optional) Run display resource-mode configuration
The resource mode configuration of the extended entry space is checked.
- Run system-view
The system view is displayed.
- Configure the resource mode of the extended entry space.
- On the S5720EI, run the assign resource-mode { enhanced-mac | enhanced-ipv4 | enhanced-ipv6 } [ slot slot-id | all ] command to configure the resource mode.
- On the S6720EI and S6720S-EI, run the assign resource-mode { enhanced-mac | enhanced-arp | enhanced-ipv4 | ipv4-ipv6 6:1 | 96k-arp } [ slot slot-id | all ] command to configure the resource mode.
By default, the resource allocation mode of the S5720EI is enhanced-mac and that of the S6720EI and S6720S-EI is enhanced-arp.

The specifications listed in the preceding table indicate the maximum number of FIB entries of a single type. Numbers of the two types of FIB entries cannot reach the maximum value simultaneously.
On the S5720EI, ARP and ND share hardware resources. The value listed in the preceding table indicates the maximum number of entries of a single type. Numbers of the two types of entries cannot reach the maximum value simultaneously.

The value listed in the preceding table indicates the maximum number of entries of a single type. Numbers of the two types of entries cannot reach the maximum value simultaneously.
When the S6720EI and S6720S-EI work in enhanced-arp, enhanced-mac, enhanced-ipv4, or 96k-arp mode, IPv4 FIB and IPv6 FIB (0-64 bits mask) share hardware resources. The value listed in the preceding table indicates the maximum number of FIB entries of a single type. Numbers of the two types of FIB entries cannot reach the maximum value simultaneously.
When the S6720EI and S6720S-EI work in ipv4-ipv6 6:1 mode, IPv6 FIB (0-64 bits mask) and IPv6 FIB (over 64 bits mask) share hardware resources. The value listed in the preceding table indicates the maximum number of FIB entries of a single type. Numbers of the two types of FIB entries cannot reach the maximum value simultaneously.
