This command displays the LDP LSPs established to, from, and through this switch. By default, ingress, egress, and transit LSPs are all displayed. By optionally specifying the LSP type, the output display is filtered to show only the type of LSPs specified.
When all LSP types are being displayed, LSPs that show only an advertised label represent egress LSPs from the network perspective or incoming LSPs from the switch perspective. LSPs that show only a received label represent ingress LSPs from the network perspective or outgoing LSPs from the switch perspective. LSPs that show both an incoming and an outgoing label represent transit LSPs. As Extreme switches are merge-capable, all LDP transit LSPs can also be used as ingress LSPs.
The significance of the VLAN information shown depends on the LSP type. For ingress and transit LSPs, the indicated VLAN is the MPLS interface used to reach the next hop peer. For egress LSPs, there is no associated MPLS next hop interface. When the prefix being advertised is associated with a local (direct) VLAN, that VLAN name is displayed. When the advertised prefix is associated with a static or an RIP route, the VLAN field is empty.
Advertised labels have switch-wide significance and are generally advertised out multiple interfaces.

Specifying the optional detail keyword displays each LSP in detail format.
Additionally, received packets and bytes are maintained for transit and egress (or incoming) LSPs. Specifying the keyword prefix and a matching ipNetmask restricts the display to a single entry.
