# PAgP Configuration

To access this dialog box:

1. Select Port > Configure > Ether Channel Configuration.

2. Click PAgP.

Use this feature to display Port Aggregate Protocol (PagP) information for the Ether Channel ports configured on this device.

Note: This dialog box is not displayed on ports with pagpEthcOperationMode set to "off(1)" or "manual(2)". In addition, the Partner Details section is only displayed on ports with pagpPartnerCount set to "one(2)" or "many(3)".

To view the definition for a particular MIB variable, click the appropriate link from the following list:

Current Interface:

Operational Mode (pagpOperationMode)

Operational mode of PAgP for this interface.

PAgP State (pagpPortState)

State of PAgP for this interface.

State Last Change Time (pagpLastStateChanged)

The time at which the pagpPortState last changed.

Hello Frequency (pagpHelloFrequency)

The time-out frequency for the PagP packet is measured as either fast or slow. When the time-out frequency is set to "fast (1)", then this device uses a 3.5 second timer to time-out receipt of a PagP packet. When the time-out frequency is set to "slow (2)", then this device uses a 105-second timer.

Distribution Algorithm (pagpDistributionAlgorithm)

The name of the method used on this interface’s aggregation port (agport) to distribute outgoing data frames among its component interfaces. The typical names are "Source MAC address", "Source and Destination Mac addresses", or "IP Flow: Source, Destination, Protocol type".

Partner Details:

No of Partners (pagpPartnerCount)

The number of other devices known to be transmitting PAgP packets to this device on this physical interface. There are three possible values:

- none(1)—The values of the remaining variables in this section are as defined by each variable.
- one(2)—The values of the remaining variables in this section are valid.
- many(3)—The values of the remaining variables in this section reflect the last PAgP packet received. The values in this section are, in this case, unreliable, as they may change with the receipt of each new PAgP packet on this interface.

Learn Method (pagpPartnerLearnMethod)

The value of the partner's pagpLearnMethod object obtained from the PAgP packet last received on this interface. The value of this object is "undefined(3)" if pagpPartnerCount is set to " none(1)".

Port Priority (pagpPartnerPortPriority)

The value of the partner's pgapPortPriority object obtained from the PAgP packet last received on this interface. The value of this object is "0" if pagpPartnerCount is set to " none(1)".

IfIndex (pagpPartnerIfIndex)

The value of the partner's ifIndex object obtained from the PAgP packet last received on this interface. The value of this object is "0" if pagpPartnerCount is set to "none(1)".

Operational Group Capability (pagpPartnerGroupCapability)

The value of the partner's pagpOperGroupCapability object obtained from the PAgP packet last received on this interface. The value of this object is "0" if pagpPartnerCount is set to "none(1)".

Agport Index (pagpPartnerGroupIfIndex)

The value of the partner's pagpGroupIfIndex object obtained from the PAgP packet last received on this interface. The value of this object is "0" if pagpPartnerCount is set to "none(1)".

Device Name (pagpPartnerDeviceName)

The display string obtained from the PAgP packet last received on this interface. This object is a zero-length string if pagpPartnerCount is set to "none(1)" or no device name has been received. The value transmitted in a PAgP information packet should be the sysName value of the device sending the packet. The maximum size of this display string is 255 octets.

Device Id (pagpPartnerDeviceId)

MAC address of the partner obtained from the PAgP packet last received on this interface. When pagpPartnerCount is set to "none(1)", the address displayed contains only zeroes.

Port Name (pagpPartnerPortName)

The display string obtained from the PAgP packet last received on this interface. This object is a zero-length string if pagpPartnerCount is set to "none(1)" or no port name has been received. The value transmitted in a PAgP packet should be the ifName value of the interface on the device sending the packet. The maximum size of this display string is 255 octets.

MAC Address (pagpPartnerAgportMACAddress)

The MAC address obtained from the pAgP packet last received on this interface. When pagpPartnerCount is set to "none(1)" or no agport MAC address has been received in a PAgP packet, the address displayed contains only zeroes. Otherwise, the device sending the TLV is promising to use the MAC address specified by this object in every frame it sends from the agport.
