Supported on all 7210 SAS platforms as described in this document
This command configures ports. Before a port can be configured, the chassis slot must be provisioned with a valid card type and the MDA parameter must be provisioned with a valid MDA type. (See card and mda commands.) All ports must be explicitly configured and enabled
Specifies the physical port ID in the slot/mda/port format.

7210 SAS-D, 7210 SAS-Dxp
This command enables DEI-based classification on access ports, network ports, access-uplink or hybrid ports.
If enabled, DEI value in the Ethernet packet header is used to determine the initial profile/color of the packet when the meter/policer used to police the FC is configured in color-aware mode. If the meter used to police the FC is configured in color-blind mode, then the DEI value of the packet has no effect. When in color-aware mode, DEI value of 0 is interpreted as in-profile or green packet and DEI value of 1 is interpreted as out-of-profile or yellow packet. In color-aware mode, the following behavior is accorded to packets classified with initial profile/color as in-profile/green and out-of-profile/yellow:
If a green packet is received and the color-aware meter is within the CIR rate, then packet is assigned a final profile of green and it is assigned a final profile of yellow if the meter exceeds the CIR rate and is within the PIR rate.
If a yellow packet is received and the color-aware meter is above the CIR rate and within the PIR rate, then the packet is assigned a final profile of yellow.
That is, in color-aware mode, yellow/out-of-profile packets cannot eat into the CIR bandwidth. It is exclusively reserved for green/in-profile packets.
The final profile assigned at ingress is used by egress to determine the WRED slope to use. The WRED slope determines whether the packet is eligible to be assigned a buffer and can be queued up on egress queue for transmission.
See the 7210 SAS-D, Dxp Quality of Service Guide for more information.

This command configures the scheduling behavior to the one specified in the policy (Strict, RR, WRR, WDRR, WRR/WDRR + Strict).

Supported on all 7210 SAS platforms as described in this document
This command configures an Ethernet port for access mode, access-uplink mode, hybrid mode, or network mode of operation.
The following modes are supported on the 7210 SAS platforms:
The 7210 SAS-D, 7210 SAS-Dxp, and 7210 SAS-K 2F1C2T support only access and access-uplink mode.
The 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C support access, access-uplink, hybrid, and network mode.
The functionality of the different modes is as follows:
Access — An access port is used for customer facing traffic on which services are configured. A Service Access Point (SAP) can only be configured on an access port. When a port is configured for access mode, the appropriate encap-type must be specified to distinguish the services on the port. When an Ethernet port has been configured for access mode, multiple services can be configured on the Ethernet port.
Access-uplink — Access-uplink ports are used to provide native Ethernet connectivity in service provider transport or infrastructure network. This can be achieved by configuring port mode as access uplink. With this option, the encap-type can be configured to only qinq. Access-uplink SAPs, which are QinQ SAPs, can only be configured on an access uplink port to allow the operator to differentiate multiple services being carried over a single access uplink port.
Network — A network port participates in the service provider transport or infrastructure network when a network mode is selected. When the network option is configured, the encap-type can be configured to either null or dot1q.
Hybrid — A hybrid Ethernet port allows the combination of network and access modes of operation on a per-VLAN basis and must be configured as either dot1q or QinQ encapsulation. When the hybrid port is configured with dot1q encapsulation, SAPs are configured in a service by providing the SAP ID, which must include the port-id value of the hybrid port and an unused VLAN tag value in the format port-id:qtag1. A SAP with the format port-id:* is also supported. Network IP interfaces are configured in the config>router>interface>port context by providing the port name, which consists of the port-id value of the hybrid port and an unused VLAN tag value in the format port-id:qtag1.
A valid value must be entered for qtag1. The port-id:* format is not supported on a network IP interface. The 4096 VLAN tag space on the port is shared among VLAN SAPs and VLAN network IP interfaces. When the hybrid port is configured with QinQ encapsulation, SAPs are configured in a service by providing the SAP ID, which must include the port-id value of the hybrid port and the outer and inner VLAN tag values in the format port-id:qtag1.qtag2. SAPS with the format port-id:qtag1.* are also supported. The outer VLAN tag value must not have been used to create an IP network interface on this port. In addition, the qtag1.qtag2 value combination must not have been used by another SAP on this port.
Network IP interfaces are configured in the config>router>interface>port context by providing the port name, which consists of the port-id value of the hybrid port and a VLAN tag value in the format port-id:qtag1.*. An outer VLAN tag qtag2 of * is used to create a network IP interface. In addition, the qtag1.qtag2 value combination must not have been used by another SAP or network IP interface on this port.
The no form of this command reverts to the default value.

network (7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C)
Specifies the Ethernet port as service access.
Specifies the Ethernet port for transport (Ethernet uplinks available only in access-uplink mode). A limited number of ports can be configured as access-uplink ports at any specified time on the 7210 SAS-Dxp.
Specifies the Ethernet port for hybrid use (available only in network mode).
Specifies the Ethernet port as service access (available only in network mode).

This command specifies the operational group to be monitored by the object under which it is configured. The oper-group name must be already configured under the config>system context before its name is referenced in this command.
The no form of this command removes the association from the configuration.
no monitor-oper-group
Specifies a character string of maximum 32 ASCII characters identifying the group instance.
mac ieee-address
no mac
config>port>ethernet
config>lag
Supported on all 7210 SAS platforms as described in this document
This command assigns a specific MAC address to an Ethernet port, Link Aggregation Group (LAG).
Only one MAC address can be assigned to a port. When multiple mac commands are entered, the last command overwrites the previous command. When the command is issued while the port is operational, IP will issue an ARP, if appropriate, and BPDUs are sent with the new MAC address. A default MAC address is assigned by the system from the chassis MAC address pool.
The no form of this command reverts the MAC address to the default value.
Specifies the 48-bit MAC address in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff where aa, bb, cc, dd, ee and ff are hexadecimal numbers. Allowed values are any non-broadcast, non-multicast MAC and non-IEEE reserved MAC addresses.
mtu mtu-bytes
no mtu
config>port>ethernet
Supported on all 7210 SAS platforms as described in this document
This command configures the maximum transmission unit (MTU) size for an Ethernet port. The Ethernet port level MTU parameter indirectly defines the largest physical packet the port can transmit or the far-end Ethernet port can receive. Packets received that are larger than the MTU value are discarded. Packets that cannot be fragmented at egress and exceed the MTU are discarded.
The value specified for the MTU includes the destination MAC address, source MAC address, the Ethertype or Length field and the complete Ethernet payload. The MTU value does not include the preamble, start of frame delimiter, or the trailing CRC.
The no form of this command reverts to the default values.
The following table describes the default MTU values that are dependent on the (sub-)port type, mode, and encapsulation.

7210 SAS-K 2F1C2T, 7210 SAS-K 2F6C4T, and 7210 SAS-K 3SFP+ 8C
This command enables Precision Time Protocol (PTP) port-based hardware timestamping on the port in both egress and ingress directions. For more information about PTP port-based hardware timestamping, including configuration guidelines, see the 7210 SAS-D, Dxp, K 2F1C2T, K 2F6C4T, K 3SFP+ 8C Basic System Configuration Guide.
The no version of this command disables PTP port-based hardware timestamping on the port.
