Will the number of multicast forwarding entries supported on each LPU change when an S series switch has different types of LPUs installed


For S series switches, if LPUs installed in a switch support different numbers of multicast forwarding entries, the number of multicast forwarding entries supported on all LPUs changes to the minimum number supported by these LPUs. It is recommended that you install only LPUs with high specifications on a switch when users connected to the switch order a large number of multicast programs.

LPUs of S series switches can be installed in any LPU slots. You can use Hardware Query Tool to query specified slots of modular switches.

LPU of S series switches
The LPUs are classified into E series Ethernet cards, F series Ethernet cards, S series Ethernet cards, B series Ethernet cards, and X series Ethernet cards. - The E series is the enhanced series that supports MPLS and extension of routing, ACL, and MAC address entries. The E series consists of EA, EC, ED, and EE LPUs. - The F series is the ordinary series that supports MPLS but not extension of MAC address entries. The F series consists of FA and FC LPUs. - The S series is the standard series that does not support extension of MAC address entries. The S series consists of SA and SC LPUs. MPLS is supported by the SC card, but not the SA card. - The B series is the large buffer series. - The X series is the agile series. The X series consists of X1E, X2E, X2S and X2H LPUs.

Are LPUs for different series of modular switches interchangeable
Most of the cards of different switches are not interchangeable. You can use Hardware Query Tool to query cards for specified models.

Whether the S-series box-type switch upgrades requires a separate upgrade of the LPU
S series box switch upgrade, only need to complete the main control board upgrade, do not need to upgrade the business board alone.

How to configure the limit on the number of entries in the forwarding table on an S series switch
For S series switches, you can run the multicast forwarding-table route-limit limit command in the system view to set the maximum number of entries in the multicast forwarding table.
