In Unified Connectivity Mode, the External Management VLAN ID should be configured to the same value as the Bearer
VLAN ID. Otherwise, it must differ from the Bearer VLAN ID.
A change in the External Management VLAN ID takes effect after the next reset.
3.5.2.2.10 Local Management IP Address
The IP address of the Local Management interface.
The default is 172.31.0.1.
It is recommended to refrain from changing the Local Management IP Address so that it can always be used as the known
default address for local management.
A change in the Local Management IP Address takes effect after the next reset.
3.5.2.2.11 Local Management Subnet Mask
The subnet mask of the Local Management interface.
The default is 255.255.255.0.
It is recommended to refrain from changing the Local Management Subnet Mask.
A change in the Local Management Subnet Mask takes effect after the next reset.
3.5.2.3 L1 & L2
The L1 & L2 option enables you to view or update the parameters of the following Ethernet ports:

DAT1 (Data Port 1): An optional 1000 Base-X optical fiber interface. Applicable only if a suitable Small Form-factor
Pluggable (SFP) optical interface is installed.

DAT2 (Data Port 2): A 10/100/1000 Base-T twisted-pair electrical interface.

DAT3 (Data Port 3): A 10/100 Base-T twisted-pair electrical interface.
The functionality of these ports depends on the Connectivity Mode (see

Out of Band Connectivity Mode: Data Port 1 or Data Port 2 is used for tagged bearer traffic (see
Mode" on page 57
tagged external management traffic and for untagged local management traffic.

In Band Connectivity Mode: Data Port 1 or Data Port 2 is used for both bearer and external management traffic. VLANs
are used to separate the two traffic types. Data Port 3 is used for untagged local management traffic.

Unified Connectivity Mode: Data Port 1 or Data Port 2 is used for both bearer and external management traffic. Both
traffic types share the same VLAN. Data Port 3 is used for untagged local management traffic.
If an SFP is installed in DAT1, the selection between Data Port 1 and Data Port 2 is based on automatic Ethernet activity
detection (only one of these ports can be active).
