Configuration Commands
Page 1350 7750 SR OS Services Guide
port-id — Specifies the physical port ID in the slot/mda/port format.
If the card in the slot has Media Dependent Adapters (MDAs) installed, the port-id must be in the
slot_number/MDA_number/port_number format. For example 6/2/3 specifies port 3 on MDA 2
in slot 6.
The port-id must reference a valid port type. When the port-id parameter represents SONET/
SDH and TDM channels, the port ID must include the channel ID. A period “.” separates the
physical port from the channel-id. The port must be configured as an access port.
If the SONET/SDH port is configured as clear-channel then only the port is specified.
qtag1, qtag2 — Specifies the encapsulation value used to identify the SAP on the port or sub-port. If
this parameter is not specificially defined, the default value is 0.
Values qtag1: 0 — 4094
qtag2 : * | 0 — 4094
The values depends on the encapsulation type configured for the interface. The following table
describes the allowed values for the port and encapsulation types.
Port Type Encap-Type Allowed Values Comments
Ethernet Null 0 The SAP is identified by the port.
Ethernet Dot1q 0 — 4094 The SAP is identified by the 802.1Q
tag on the port. Note that a 0 qtag1
value also accepts untagged packets on
the dot1q port.
Ethernet QinQ qtag1: 0 — 4094
qtag2: 0 — 4094
The SAP is identified by two 802.1Q
tags on the port. Note that a 0 qtag1
value also accepts untagged packets on
the dot1q port.
SONET/SDH IPCP - The SAP is identified by the channel.
No BCP is deployed and all traffic is
IP.
SONET/SDH
TDM
BCP-Null 0 The SAP is identified with a single
service on the channel. Tags are
assumed to be part of the customer
packet and not a service delimiter.
SONET/SDH
TDM
BCP-Dot1q 0 — 4094 The SAP is identified by the 802.1Q
tag on the channel.
SONET/SDH
TDM
Frame Relay 16 — 991 The SAP is identified by the data link
connection identifier (DLCI).
