Step 24
Check the Protocol Tunnelling check box (see
) if you want to define the Layer 2 Bridge
Protocol Data Unit (BPDU) frames that can be tunneled over the core to the other end.
Figure 7-19
Protocol Tunnelling
For each protocol that you check, enter the shutdown threshold and drop threshold for that protocol:
a.
Enable cdp—Enable Layer 2 tunnelling on Cisco Discover Protocol (CDP).
b.
cdp shutdown threshold—Enter the number of packets per second to be received before the
interface is shut down.
c.
cdp drop threshold—Enter the number of packets per second to be received at which point the
interface will start dropping CDP packets.
d.
Enable vtp—Enable Layer 2 tunnelling on VLAN Trunk Protocol (VTP).
e.
vtp shutdown threshold—Enter the number of packets per second to be received before the
interface is shut down.
f.
vtp drop threshold—Enter the number of packets per second to be received at which point the
interface will start dropping VTP packets.
g.
Enable stp—Enable Layer 2 tunnelling on Spanning Tree Protocol (STP).
h.
stp shutdown threshold—Enter the number of packets per second to be received before the
interface is shut down.
i.
stp drop threshold—Enter the number of packets per second to be received at which point the
interface will start dropping STP packets.
j.
Recovery Interval—Enter the amount of time, in seconds, to wait before recovering a UNI port.
Step 25
Check the N-PE Pseudo-wire On SVI check box to configure the pseudowire connection on the
switched virtual interface of the OSM card.
