(8) IGMP snooping and MLD snooping
The following table shows the capacity limits for IGMP/MLD snooping. Multicast MAC
addresses learned in IGMP/MLD snooping are registered in the MAC address table. The
following table shows the number of multicast MAC addresses that can be registered.
Table 3-17 Capacity limits of IGMP/MLD snooping
Item
Number of configured VLANs
#2, #3
Registered entries
#1
The sum of the ports on which IGMP/MLD snooping operates (sum of ports included
in the VLANs configured for IGMP/MLD snooping) cannot be larger than 512 for all
devices. For example, if IGMP/MLD snooping is enabled in 16 VLANs, each of which
has 10 ports, there will be 160 IGMP/MLD snooping-enabled ports.
#2
This value is the sum of the number of multicast MAC addresses learned in each
VLAN.
#3
The number of entries means the total number of entries used in IGMP/MLD
snooping. If both IGMP snooping and MLD snooping are set for the same VLAN, the
number of VLANs is 2.
(9) Number of interfaces
In the Switch, you can assign IP addresses to VLANs. This subsection describes the
maximum number of VLAN interfaces to which IP addresses can be assigned. It also
explains the maximum number of assignable IP addresses.
(a) Maximum number of interfaces
The table below describes the maximum number of interfaces supported by the Switch.

(b) Maximum number of multi-homed subnets
The Switch does not support multihoming.
(c) Maximum number of IP addresses
(i) IPv4 addresses
The table below describes the maximum number of IPv4 addresses that can be set per
switch by a configuration command.
