Modifying and displaying Layer 3 system parameter limits
• Number of hardware logical interfaces (physical port and VLAN pairs) – This value is the same
as the maximum number of VLANs supported systemwide, so it is not configurable nor
displayed in the show default value output in second generation modules.
• Number of multicast output interfaces (clients) – 3072 maximum. This value is fixed in second
generation modules and cannot be modified. This system parameter occupies its own
hardware memory space.
To display the current settings for the Layer 3 system parameters, use the show default value
command. Refer to “Displaying Layer 3 system parameter limits” on page 1191.
FastIron third generation modules
The default value of next hop entries on FastIron X Series devices with the following third
generation modules installed is 16384. This value is predefined and not editable.
• SX-FI48GPP
• SX-FI-2XG
• SX-FI-8XG
• SX-FI-24HF
• SX-FI-24GPP
If the FastIron X Series device is installed with first generation or second generation modules, the
system automatically calculates the default value for these modules.
Displaying Layer 3 system parameter limits
To display the Layer 3 system parameter defaults, maximum values, and current values, enter the
show default value command at any level of the CLI.
The following example shows output on a FastIron X Series with first generation modules.
