Chapter 29 Layer 2 Protocol Tunneling Table 90 Advanced Application > Layer 2 Protocol Tunneling (continued) LABEL STP VTP Point to Point DESCRIPTION Select this option to have the Switch tunnel STP (Spanning Tree Protocol) packets so that STP can run properly across the service provider's network and spanning trees can be set up based on bridge information from all (local and remote) networks. Select this option to have the Switch tunnel VTP (VLAN Trunking Protocol) packets so that all customer switches can use consistent VLAN configuration through the service provider's network. The Switch supports PAgP (Port Aggregation Protocol), LACP (Link Aggregation Control Protocol) and UDLD (UniDirectional Link Detection) tunneling for a point-to-point topology. PAGP LACP UDLD Mode Both PAgP and UDLD are Cisco's proprietary data link layer protocols. PAgP is similar to LACP and used to set up a logical aggregation of Ethernet ports automatically. UDLD is to determine the link's physical status and detect a unidirectional link. Select this option to have the Switch send PAgP packets to a peer to automatically negotiate and build a logical port aggregation. Select this option to have the Switch send LACP packets to a peer to dynamically creates and manages trunk groups. Select this option to have the Switch send UDLD packets to a peer's port it connected to monitor the physical status of a link. Select Access to have the Switch encapsulate the incoming layer-2 protocol packets and forward them to the tunnel port(s). Select Access for ingress ports at the edge of the service provider's network. Apply Cancel Note: You can enable L2PT services for STP, LACP, VTP, CDP, UDLD, and PAGP on the access port(s) only. Select Tunnel for egress ports at the edge of the service provider's network. The Switch decapsulates the encapsulated layer-2 protocol packets received on a tunnel port by changing the destination MAC address to the original one, and then forward them to an access port. If the service(s) is not enabled on an access port, the protocol packets are dropped. Click Apply to save your changes to the Switch's run-time memory. The Switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the non-volatile memory when you are done configuring. Click Cancel to begin configuring this screen afresh. 244 MES3500-24/24F User's Guide

Chapter 29 Layer 2 Protocol Tunneling
MES3500-24/24F User’s Guide
244
STP
Select this option to have the Switch tunnel STP (Spanning Tree Protocol) packets so that
STP can run properly across the service provider’s network and spanning trees can be set up
based on bridge information from all (local and remote) networks.
VTP
Select this option to have the Switch tunnel VTP (VLAN Trunking Protocol) packets so that all
customer switches can use consistent VLAN configuration through the service provider’s
network.
Point to Point
The Switch supports PAgP (Port Aggregation Protocol), LACP (Link Aggregation Control
Protocol) and UDLD (UniDirectional Link Detection) tunneling for a point-to-point topology.
Both PAgP and UDLD are Cisco’s proprietary data link layer protocols. PAgP is similar to
LACP and used to set up a logical aggregation of Ethernet ports automatically. UDLD is to
determine the link’s physical status and detect a unidirectional link.
PAGP
Select this option to have the Switch send PAgP packets to a peer to automatically negotiate
and build a logical port aggregation.
LACP
Select this option to have the Switch send LACP packets to a peer to dynamically creates
and manages trunk groups.
UDLD
Select this option to have the Switch send UDLD packets to a peer’s port it connected to
monitor the physical status of a link.
Mode
Select
Access
to have the Switch encapsulate the incoming layer-2 protocol packets and
forward them to the tunnel port(s). Select
Access
for ingress ports at the edge of the
service provider's network.
Note: You can enable L2PT services for STP, LACP, VTP, CDP, UDLD, and PAGP on the
access port(s) only.
Select
Tunnel
for egress ports at the edge of the service provider's network. The Switch
decapsulates the encapsulated layer-2 protocol packets received on a tunnel port by
changing the destination MAC address to the original one, and then forward them to an
access port. If the service(s) is not enabled on an access port, the protocol packets are
dropped.
Apply
Click
Apply
to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the
Save
link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
