Hello,
Yes the limitation is related of the equipment capability , you can check the capability of the Equipment from HedEX
search in the ( Feature Description) then in Ethernet Features> MPLS Basics and PWE3
there you can find the number of available PW and Tunnels in the level of the equipment and board , they dont mention it for port but I think they are the same for the port.
as Example OSN1800
SS-PW:64 x 1024/NE 64 x 1024/board
MS-PW: 32 x 1024/NE 32 x 1024/board
|
| Maximum number of tunnel | 64 x 1024/NE 64 x 1024/board
|
for other NEs its different
