5.3.13.3 LAG and VCS Support
The Physical Network Map shows the discovered devices and the physical connections (links) between them. The physical
link icon between devices appears if the both devices support LLDP, and the NMS actively supports the LLDP functionality of
the device.
Note: The physical links can also be manually created using the Link Operation function. Refer to 6.2.4.
On this Map, there is a feature that shows the LAG and Virtual Chassis Stacking (VCS) configuration.
• Stacked Devices - If a device is discovered to be set in a stacked configuration, its node will be rendered as two node
icons stacked on top of each other, regardless of how many units comprise the stack. Moreover, the outline of the
bottom icon is rendered blue if the stack is functioning normally, and orange if one or more members of the stack is
unavailable. Refer to the following figure.

• LAG - If two or more links are aggregated, forming a LAG connection, the LAG link is rendered as two parallel lines.
Moreover, if both links are rendered as green, all links are available. If one of the two links is orange, then:
• One or more links of the LAG is unavailable.
• The neighboring port is not configured for LAG.
• (AlliedWare type devices) - The port is not associated to any LACP channel.
Refer to the following figure.
FIGURE 5-66 Icons for LAG links
• Layer 2 Links Screen - This screen shows the attributes of the links for the device and allows the user to create and add
links. (You can access the this screen by right clicking on a device and selecting Network Services -> Link Operations.) The
Link Type indicates LAG, as shown the following figure.
