On the equipment tree, expand Network→NE→Shelf→Card Slot n→Daughter Card Slot n→Port n/n/n.

Right-click on the Port icon and choose Properties. The Physical Port (Edit) form opens.

Configure the required general parameters.

Only one MAC address can be assigned to a port. When a new MAC address is configured while the port is operational, IP issues an ARP, if appropriate, and BPDUs are sent with the new MAC address. A default MAC address is assigned by the system.

If the port is a LAG member, the Hold Time Up (seconds) parameter is configurable only if the port is the primary member. The Hold Time Down (seconds) parameter is not configurable when the port is a LAG member.

When you set a DWDM Channel, the other DWDM parameters are populated. You cannot configure the DWDM channel if frequency is configured under the DWDM Optics tab. DWDM channel and frequency configuration are mutually exclusive.

The DDM Event Suppression parameter is configurable only on ports on SFPs and XFPs optical modular transceivers.

You cannot change the Mode parameter when the Enable DEI parameter is selected.

When you set the Mode parameter to Hybrid, you cannot set the Encapsulation Type parameter to Null.

The MTU value for a port is associated with the port mode and the port encapsulation type. By default, the MTU of a hybrid port is set to the larger of the network and access MTUs.

You cannot deselect the Enable DEI parameter on a port when SAPs on that port are configured with color-aware meters. If you deselect the Enable DEI parameter, the ingress policies assigned to SAPs on the port must be configured with meters whose Color Mode parameter is set to Color Blind. See To configure a 7210, 7250, and 1830 SAP Access Ingress policy .

Consider the following when you configure the Enable DEI parameter on a hybrid port.

• When the Enable DEI parameter is selected, the network policy assigned to the port must be configured to use DEI as the profile. The Default FC Profile parameter and the Profile parameter on the Ingress Dot1p tab in the policy must be set to the DEI option. See To configure a 7210 and 1830 network policy .

• You cannot select Enable DEI and assign a DEI-configured network policy in the same configuration process. You must first assign the network policy with the Default FC Profile and Profile parameters set to the DEI option, and apply the change. Then you can subsequently select the Enable DEI parameter.

If you set the Mode parameter to Hybrid, configure the required parameters in the Hybrid Ingress Buffer Allocation and the Hybrid Egress Buffer Allocation panels, as required.

If you change the Mode parameter from Access to Hybrid and there are SAPs on the port, perform To migrate SAPs from access mode to hybrid mode to migrate the SAPs.

If you are configuring a 7210 SAS Ethernet port, you can add the port to an SHG on supporting NEs. See To create a 7210 SAS SHG for information about creating an SHG.

Note: A port cannot be added to or deleted from an SHG if it has a SAP configured on it or is a member of a LAG.

A port cannot belong to more than one SHG; you must remove any SHGs from the port before you can add the port to a different SHG.

Configure the Named Pool Buffer Policy for the port in the Named Buffer Pool panel.

Note: The types of policies that you can choose depend on the type of NE, daughter card, and the mode type of the port you are configuring.

• The Network Queue and Accounting Policies panel are only displayed for network and hybrid ports.

• The Port Scheduler panel is only displayed for ports on non-HSMDA daughter cards.

• The HSMDA Egress Scheduler panel is only displayed for ports on HSMDA daughter cards. HSMDA is only supported on 7750 SR-7/12/12e and 7450 ESS-7/12, Release 20.10 and earlier.

If you are configuring an access port on a 7210 SAS-E for the collection of packet forwarding statistics on egress queues, configure the required parameters in the Egress Packets Forwarding panel.

For the 7210 SAS-E, access ports always contain eight queues. You can enable up to eight queues on any port for the collection of packet forwarding statistics. However, only eight counters can be enabled for each 7210 SAS-E device. If no queues are enabled on a port, no accounting statistics are collected for that port.

If you are configuring a 7210 SAS Ethernet port, perform To assign QoS policies to a 7210 SAS Ethernet port , then go to Step 20 .

Select a network queue policy for the port, if applicable.

The RS-FEC Mode parameter is configurable in the NFM-P for supported physical ports and breakout ports. The RS-FEC Mode is configurable for physical ports under the Ethernet tab. For breakout ports, the RS-FEC Mode parameter is configurable either under the Ethernet tab of the breakout port or under the General tab of its connector port. After the RS-FEC Mode is configured, the RS-FEC Oper Mode can be viewed in the General tab.

On the 7210 SAS-X, configure the Egress Scheduler Mode parameter to choose FC-based or SAP-based scheduling for access ports.

For access ports on supporting 7210 SAS NEs, configure overrides for queues in the Port Access Egress policy assigned to the port; see To configure QoS policy overrides on port access egress queues for a 7210 SAS.

For 7210 SAS NEs, ports can forward multicast data packets to either L2 or L3 interfaces, but not both. Configure the Multicast Ingress parameter according to your forwarding requirements.

Management connectivity between the NFM-P and the 7705 SAR may be lost if a line loopback is applied to an Ethernet port that is carrying in-band management traffic. The line loopback remains in effect until the timer expires and the 7705 SAR removes the loopback.

Statistics are collected for IEEE 1588 PTP timestamps only when the Timestamp Capable parameter is enabled on the 7705 SAR-A, 7705 SAR-Ax, and the 7705 SAR-W.

If you are configuring a 7705 SAR-Wx and the port supports DSL, the EFM-OAM tab appears. Perform the required steps in To configure an 802.3ah EFM OAM diagnostic test from an NE Properties form to configure the EFM-OAM tab.

On the 7250 IXR, the Timed Loopback Type parameter must be configured while enabling Swap Mac Address. Internal loopback is only supported in access or hybrid mode, and line loopback is supported in access or network mode.  You cannot configure the Timed Loopback Type parameter when the Received Remote Loopback Requests parameter is set to Processed.

Select the Hardware Aggregate Shaper Scheduler policy.

Configure a port loopback on a 7210 SAS device.

1. If you are configuring a port loopback with MAC swap, you must first configure a no-service loopback port. See To configure a no-service loopback port on the 7210 SAS .
