Hierarchy Level


Create dynamic profiles for use with DHCP or PPP client access.



Name of the dynamic profile; string of up to 80 alphanumeric characters.


(Optional) Enables IPv4 reassembly of fragmented GRE packets conveyed across a soft GRE tunnel from a Wi-Fi access point to a Wi-Fi access gateway on a BNG. Reassembly is supported for fragments that range in size from 256 bytes through 8192 bytes.

  • The maximum reassembled packet size is 13,310 bytes; this requires an MTU of 1500 bytes. The router drops reassembled packets that are larger than 13,310 bytes. The router also drops DHCP discover packets that are smaller than the MTU.

  • Ordering is not maintained between fragmented packets and non-fragmented packets.

  • The WAG does not support soft GRE packets with keys. Fragmented packets GRE with key are not reassembled.

  • Soft GRE packet reassembly is not supported for pseudowires over redundant logical tunnels (RLT).

  • The order of the last arriving fragment is not guaranteed when the reassembled packets are forwarded.

The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.
