PVP Connections

Virtual Ports and Static Connections

2.Use the set portconfig command to turn off signaling and ILMI and to specify bits for VPIs on port 7b1:

SmartSwitch # set portconfig

 

 

PortNumber()

: 7b1

— Specify the second port

PortAdminStatus(up)

:

 

IlmiAdminStatus(up)

: down

 

SigType()

: nnipvc

 

SigRole(network)

:

 

InterfaceType(private)

:

— 1 bit for VPIs: 2 1-1 = 1 VPI

MaxVpiBits(0)

: 1

MaxVciBits(12)

3.Use the add pvp command to create the pvp connection:

SmartSwitch # add pvp

 

 

ConnType(PTP)

:

— See note below

Port-1-Number()

: 7a4

— Specify the first port

Port-1-VPI()

: 1

— Specify its VPI

Port-2-Number()

: 7b1

— Specify the second port

Port-2-VPI()

: 1

— Specify its VPI

Port1-to-Port2TrafficDescriptorIndex()

: 2

— Set the traffic descriptors

Port2-to-Port1TrafficDescriptorIndex()

: 2

Note Point-to-multipoint PVPs are currently not supported on the SmartSwitch 6500.

4.Use the show pvp command to display the PVP connection:

SmartSwitch # show pvp

In the example above, we stopped ILMI and signaling on the ports used for the PVP. Stopping ILMI and signaling is characteristic of a “true” PVP connection. However, if necessary, a PVP can be created between ports running ILMI and signaling. In this case, the PVP coexists with the rest of the connections (if any) established across the connection.
