Modifying and displaying layer 3 system parameter limits
This section shows how to view and configure some of the Layer 3 system parameter limits.
Configuration notes
Changing the system parameters reconfigures the device memory. Whenever you reconfigure
the memory on a Dell PowerConnect device, you must save the change to the startup-config
file, then reload the software to place the change into effect.
The Layer 3 system parameter limits for PowerConnect IPv6 models are automatically
adjusted by the system and cannot be manually modified. Refer to “PowerConnect IPv6
models” on page 625.
PowerConnect IPv6 models
PowerConnect IPv6 models support the same Layer 3 system parameters that use hardware
memory, as do PowerConnect IPv4 models. However, there are some configuration differences for
IPv6 models versus IPv4 models. The differences are as follows:
Number of IP next hops and IP route entries – 6144 maximum and default value. The system
automatically calculates this value, based on the maximum number of VLANs supported
system-wide.
Number of hardware logical interfaces (physical port and VLAN pairs) – This value is the same
as the maximum number of VLANs supported system-wide, so it is not configurable nor
displayed in the show default values output in IPv6 models.
Number of multicast output interfaces (clients) – 3072 maximum. This value is fixed in IPv6
models 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 625.
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 shows an example output on a IPV4 device.
