Configuring the Resource Mode of Extended Entry Space

Configuring the Resource Mode of 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.

NOTE:

Only the S5720EI, S5720HI, S5730HI, S6720HI, S6720EI and S6720S-EI support this configuration.

Procedure

  1. (Optional) Run display resource-mode configuration

    The resource mode configuration of the extended entry space is displayed.

  2. Run system-view

    The system view is displayed.

  3. 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, S6720S-EI, run the assign resource-mode { enhanced-mac | enhanced-arp | enhanced-ipv4 | ipv4-ipv6 6:1 | super-arp } [ slot slot-id | all ] command to configure the resource mode.
    • On the S6720HI, run the assign resource-mode { enhanced-mac | enhanced-arp | enhanced-ipv4 | enhanced-ipv6 | limiting-mac | eca } [ 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 S5720HI, S5730HI, S6720HI, S6720EI, and S6720S-EI is enhanced-arp.

    Table 2-1  Number of entries supported in different resource allocation modes on the S5720EI
    Resource Allocation Mode MAC IPv4 FIB IPv6 FIB (0-64 Bits Mask) IPv6 FIB (Over 64 Bits Mask) ARP ND Multicast IPv4 Multicast IPv6 Number of NAC Users
    enhanced-mac(Default) 64K 12K 6K 1K 16K 8K 4000 2000(Share with Multicast IPv4) 2K

    enhanced-ipv6 32K 8K 4K 2K 16K 8K 4000 2000(Share with Multicast IPv4) 2K
    NOTE:
    • On the S5720EI, IPv4 FIB and IPv6 FIB (0-64 bits mask) share hardware resources. 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.

    super-arp 96K 12K 6K 1K 128K 48K 4000 2K
    NOTE:
    • On the S6720EI, S6720S-EI, 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.
    • When the S6720EI and S6720S-EI work in enhanced-arp, enhanced-mac, enhanced-ipv4, or super-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.
    • On the S6720EI and S6720S-EI, if the assign resource-mode command sets the resource allocation mode to enhanced-ipv4 or ipv4-ipv6 6:1, and the ipv4 destination-unreachable drop or ipv6 destination-unreachable dropcommand has been executed, the function that dropping the packets that do not match routing entries does not take effect.
    • On the S6720EI, S6720S-EI, redirection to a low-priority next hop is not supported in enhanced-ipv4 or ipv4-ipv6 6:1 resource allocation mode.
    • On the S6720EI, S6720S-EI, MPLS is not supported in super-arp resource allocation mode.

    NOTE:

    On the S6720HI, 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. For example, ARP and FIBv4 share hardware resources, while ND and FIBv6 share hardware resources.

    After the resource mode is set to limiting-mac on the S6720HI, the S6720HI cannot function as an authentication point for user access.
