radius-server accounting-merge max-length

Function

The radius-server accounting-merge max-length command sets the maximum length for a post-merging accounting packet for value-added services.

The undo radius-server accounting-merge max-length command deletes the maximum length set for a post-merging accounting packet for value-added services.

By default, no maximum length is set for a post-merging accounting packet for value-added services.

This command is supported only on the NetEngine 8000 F1A.

Format

Usage Guidelines

Usage Scenario

The length of a post-merging accounting packet for value-added services may exceed the MTU of an intermediate device. If an intermediate device does not have packet fragmentation, a post-merging accounting packet is discarded. To resolve this issue, run the radius-server accounting-merge max-length command to set the maximum length for a post-merging accounting packet for value-added services.

Precautions

In VS mode, this command is supported only by the admin VS.

The maximum length set using this command takes effect only for a post-merging accounting packet that contains two or more value-added services. If a post-merging accounting packet contains only one value-added service, the packet is considered a non-merging packet.

By default, the maximum length of a post-merging accounting packet is the same as that of a non-merging packet, which is controlled using the radius-server packet send max-length enhance command in the system view.

If the radius-server accounting-merge max-length command is run in the RADIUS server group view to set the maximum length for a post-merging accounting packet for value-added services and the radius-server packet send max-length enhance command is run in the system view to specify the maximum length (2048 bytes by default) for a RADIUS packet, the smaller value between the two maximum lengths is used as the maximum length for a post-merging accounting packet for value-added services.

Example

# Set the maximum length to 1480 bytes for a post-merging accounting packet for value-added services.
