Configuring physical ports with CLI
This section provides information to configure cards, MDAs, and ports.
Preprovisioning guidelines
SR OSs have a console port, either located on the CPM or CCM, or integrated into the chassis (on the 7750 SR-c4 models), to connect terminals to the router.
Configure command options from a system console connected to a router console port, using Telnet to access a router remotely or SSH to open a secure shell connection.
Predefining entities
To initialize a card, the chassis slot, line card type, and MDA type must match the preprovisioned command options. In this context, preprovisioning means to configure the entity type (such as the card type, MDA type, port, and interface) that is planned for a chassis slot, card, or MDA. Preprovisioned entities can be installed but not enabled or the slots can be configured but remain empty until populated. Provisioning means that the preprovisioned entity is installed and enabled.
You can:
Preprovision ports and interfaces after the line card and MDA types are specified.
Install line cards in slots with no pre-configuration command options specified. After the card is installed, the card and MDA types must be specified.
Install a line card in a slot provisioned for a different card type (the card does not initialize). The existing card and MDA configuration must be deleted and replaced with the current information.
Preprovisioning a port
Before a port can be configured, the slot must be preprovisioned with an allowed card type and the MDA must be preprovisioned with an allowed MDA type. Some recommendations to configure a port include:
-
Ethernet
-
Configure an access port for customer facing traffic on which services are configured.
-
An encapsulation type may be specified to distinguish services on the port or channel. Encapsulation types are not required for network ports.
-
To configure an Ethernet access port, see Configuring Ethernet access ports.
-
-
SONET/SDH
-
SONET/SDH can be used only when configuring OC-3 and OC-12 SONET paths.
-
To configure a SONET path, see Configuring SONET/SDH ports.
-
Configure a network port or channel to participate in the service provider transport or infrastructure network.
-
Accounting policies can only be associated with network ports/channels and Service Access Ports (SAPs). Accounting policies are configured in the following context.
configure log accounting-policy -
To configure an Ethernet network port, see Configuring Ethernet network ports.
-
-
channelized
Channelized ports can only be configured on TDM satellites such as the channelized OC-3-SFP or channelized OC-12-SFP.
Maximizing bandwidth use
After ports are preprovisioned, Link Aggregation Groups (LAGs) can be configured to increase the bandwidth available between two nodes.
All physical links or channels in a LAG/bundle combine to form one logical connection. A LAG/bundle also provides redundancy in case one or more links that participate in the LAG/bundle fail. To configure channelized port for Sonet/SDH high speed channels (ASAP MDAs only), see Configuring SONET/SDH ports. For command syntax for LAG, see Configuring LAG.
Basic configuration
The most basic configuration must specify the following:
-
chassis slot
-
line card type (must be an allowed card type)
-
MDA slot
-
MDA (must be an allowed MDA type)
-
specific port to configure
The following is an example of card configuration for the 7750 SR.

----------------------------------------------Configuring ports
This section provides the CLI and examples to configure port command options.
Configuring port pools
The buffer space is portioned out on a per port basis. Each port gets an amount of buffering which is its fair-share based on the port’s bandwidth compared to the overall active bandwidth.
This mechanism takes the buffer space available and divides it into a portion for each port based on the port’s active bandwidth relative to the amount of active bandwidth for all ports associated with the buffer space. The number of ports sharing the same buffer space depends on the type of MDAs populated on the IOM. An active port is considered to be any port that has an active queue associated. After a queue is created for the port, the system allocates the appropriate amount of buffer space to the port. This process is independently performed for both ingress and egress.
Normally, the amount of active bandwidth is considered as opposed to total potential bandwidth for the port when determining the port’s fair share. If a port is channelized and not all bandwidth is allocated, only the bandwidth represented by the configured channels with queues configured is counted toward the bandwidth represented by the port. Also, if a port may operate at variable speeds (as in some Ethernet ports), only the current speed is considered. Based on the above, the number of buffers managed by a port may change because of queue creation and deletion, channel creation and deletion and port speed variance on the local port or other ports sharing the same buffer space.

configure port 1/2/1 modify-buffer-allocation-rate egr-percentage-of-rate 200The default buffer allocation has the following characteristics:
-
Each port manages a buffer according to its active bandwidth (ports with equal active bandwidth get the same buffer size).
-
An access port has 2 default pools created: access-ingress and access-egress.
-
A network port has 2 default pools created: ingress-FP (common pool for all ingress network ports) and network-egress.
-
All queues defined for a port receive buffers from the same buffer pool.
The following example shows port pool configurations.
MD-CLI

Changing the APS configuration
APS configuration rules:
-
A working port must be added first. Then a protection port can be added or removed at any time.
-
A protection port must be administratively disabled before being removed from an APS group.
-
A path cannot be configured on a port before the port is added to an APS group.
-
A working port cannot be removed from an APS group until the APS port path is removed.
-
When ports are added to an APS group, all path-level configurations are available only on the APS port level and configuration on the physical member ports are blocked.
-
For a multichassis APS group, only one member circuit (either working or protect) can be added. Note that the neighbor IP address of an APS group must be configured before adding a member circuit in it. The configuration of a non-zero neighbor IP address indicates the APS group as multichassis. Thus, the member circuit and services must be removed before adding or removing the neighbor IP address (for example, before converting an APS group from multichassis to single-chassis or single-chassis to multichassis).
The following shows an example configuration for a TDM SC-APS group using SONET/SDH channelization, and a Cpipe service using an APS SAP and a physical TDM SAP.

Configuring Ethernet access ports
Services are configured on access ports that are used for customer-facing traffic. If a SAP is to be configured on a port, it must be configured as access mode. When a port is configured for access mode, the appropriate encapsulation type can be specified to distinguish the services on the port. After a port has been configured for access mode, multiple services can be configured on the port.
The following example shows an Ethernet access port configuration.
MD-CLI

Configuring SONET/SDH ports
Only the TDM satellite has native SONET/SDH ports.
When an Ethernet port is configured in WAN mode (xgig wan), you can change specific SONET/SDH command options to reflect the SONET/SDH requirements for this port.
The following CLI output shows an example of a SONET/SDH configuration for a WAN PHY Ethernet port.

Verify the MDA type
To ensure that you have a channel-capable MDA, verify that the MDA-type you are configuring by entering a show mda command.
The MDAs shown in the MDA Provisioned column in the following output are a 12-port channelized DS3 MDA (m12-ds3) on card 1, MDA slot 1, and a 1-port channelized OC12-SFP MDA (m1-choc12-sfp) on card 1, MDA slot 2.

The following shows an example to configure a channelized port on a 1-port channelized OC-12-SFP MDA.
A:node-2>config# port 5/2/1
At this level you must choose the tributary. When provisioning nodes on a channelized OC-12 MDA, you must provision the parent STS1-1 SONET path first.
The following example shows the output.

Configuring LAG
LAG configurations should include at least two ports. Other considerations include the following.
-
A maximum of 64 ports (depending on the lag-id) can be included in a LAG. All ports in the LAG must share the port characteristics inherited from the primary port.
-
Auto-negotiation must be disabled or set to limited mode for ports that are part of a LAG, to guarantee a specific port speed.
-
Ports in a LAG must be configured as full duplex.
The following example shows the LAG configuration output.
MD-CLI
[ex:/configure lag "lag-2"]

----------------------------------------------Configuring BFD on LAG links
BFD can be configured under the LAG context to create and establish the micro-BFD session per link after the LAG and associated links have been configured. An IP interface must be associated with the LAG or a VLAN within the LAG, if dot1q encapsulation is used, before the micro-BFD sessions can be established.
The following contexts are used to configure BFD over LAG links:
- MD-CLI
configure lag bfd-liveness family - classic
CLI
configure lag bfd family
When configuring the local and remote IP address for the BFD over LAG link sessions, the local-ip-address value should always match an IP address associated with the IP interface to which this LAG is bound. In addition, the remote-ip-address value should match an IP address on the remote system and should also be in the same subnet as the local-ip-address. If the LAG bundle is re-associated with a different IP interface, the local-ip-address and remote-ip-address values should be modified to match the new IP subnet. The local-ip-address and remote-ip-address values do not have to match a configured interface in the case of tagged LAG/ports.
Configuring the following optional command options for the BFD over LAG links is supported.
-
transmit-interval
This command option specifies the transmit timer interval used for micro-BFD session over the associated LAG links.
-
receive-interval
This command option specifies the receive interval timer used for micro-BFD session over the associated LAG links.
-
multiplier
This command option specifies the detect multiplier used for a micro-BFD session over the associated LAG links.
-
max-setup-time
This command option specifies how long a link remains active if BFD is enabled after the LAG and associated links are active and in a forwarding state.
-
max-admin-down-time
This command option specifies how long the system waits before bringing the associated link out of service if an ADMIN-DOWN state message is received from the far end.
Perform the following steps to enable and configure BFD over the individual LAG links:
- Enable BFD within the LAG context, which also enters the CLI into the BFD context.
- Configure the address family for the micro-BFD sessions. Only one address family can be configured per LAG.
- Configure the local IP address for the BFD sessions.
-
Configure the remote IP address for the BFD sessions.

Configuring G.8031 protected Ethernet tunnels
Ethernet tunnel configuration can include at most two paths. Other considerations include:
-
A path contains one member port and one control-tag (backbone VLAN ID/BVID).
-
If the user wants to replace an existing member port or a control-tag, the whole path needs to be shutdown first. The alternate path is activated as a result keeping the traffic interruption to a minimum. Then the whole path must be deleted and re-created. To replace an existing member port or control tag, the whole path needs to be shutdown first. The alternate path is activated as a result keeping traffic interruption to a minimum. Then the whole path must be deleted, the alternate path precedence modified to primary before re-creating the new path.
-
The Ethernet tunnel inherits the configuration from the first member port. The following port-level configuration needs to be the same between member ports of an Ethernet tunnel:
configure port ethernet access egress queue-group configure port access egress pool configure port ethernet dot1q-etype configure port ethernet qinq-etype configure port ethernet pbb-etype configure port ethernet mtu- MD-CLI
configure port ethernet egress port-scheduler-policy - classic
CLI
configure port ethernet egress-scheduler-policy
- MD-CLI
-
The user can update these port command options only if the port is the sole member of an Ethernet tunnel. This means that in the example that follows, the user needs to remove port 1/1/4 and port 1/1/5 before being allowed to modify 1/1/1 for the preceding command options.
classic CLI
A:node-2>config# eth-tunnel 1

Configuring connectors and connector ports
Some assemblies have support for QSFP28 or QSFP-DD transceiver modules. These modules have different variants, some of which provide multiple physical ports out of a single module (breakout modules). There is a QSFP28 breakout module that supports ten physical 10 Gb Ethernet ports. On assemblies that support these breakout variants, the front panel cages are modeled as connectors instead of as direct ports. The connector must be configured for the type of breakout module that is to be inserted and then the appropriate ports are created and can be configured. The options for breakout on specific connectors depend on both the card type and level (or XMA type and level). See the applicable installation guides for details.
The connector reference is in the format slot/mda/connector (for example, 1/1/c3) and the ports owned by the connector use the format slot/mda/connector/port. For example, in a 7750 SR-1 with the 6-port QSFP28 mda-e-xp installed in the first MDA slot, initially there are no ports available, only six connectors:
Use the following command to display the MDA information.
