Port Pairs
A port-pair is a bidirectional connection in which traffic arriving on one port in the pair is transmitted out the other (and vice-versa) as a passthrough TAP. Keep in mind the following rules and notes for port-pairs:
|
■
|
You can configure whether a port-pair uses link status propagation. Link port propagation does the following: |
|
o
|
Enabled—when one port in the pair goes down, the other port goes down. |
|
o
|
Disabled—when one port in the pair goes down, the other port is unaffected. |
|

Port-pairs can be established between ports using different speeds. For example, from a 100Mb port to a 1Gb port. However, the system will warn you when creating such port-pairs. Depending on traffic volume, port-pairs between ports using different speeds can cause packet loss when going from a faster port to a slower port. For example, going from 1Gb to 100Mb, from 10Gb to 1Gb, and so on. |
Create Port Pair
To configure a port pair, do the following:
|
1.
|
Select Ports > Port Pairs. |
|
3.
|
On the Port Pair page, do the following: |
|
a.
|
(Optional) Type an alias in the Alias field to help identify this port pair. |
|
b.
|
(Optional) Type a description in the Description field. |
|
c.
|
Click in the First Port field and select a network port. |
|
d.
|
Click in the Second Port field and select another network port. |
|
e.
|
(Optional) Enable Link Failure Propagation. |
Port pairs can operate with or without line failure propagation (LFP) as follows:
|
•
|
With LFP enabled, link failure on one of the ports in the port pair automatically brings down the opposite side of the port pair. |
|
•
|
With LFP disabled, the opposite port is not brought down automatically. |
Note: A port pair created on a copper TAP has LFP enabled by default.
Use the following buttons to manage the Port Pairs.

Tags
|
Use to associate tags to Port Pairs and to remove the tags from Port Pairs when not required.
To add tags:
|
1.
|
Select the required Port Pairs to which the tags must be applied. |
|
2.
|
Click the Tags drop-down menu button and select Add. |
|
3.
|
In the Add Tags to Resources page, select the required Tag Keys and Tag Values. |
|
4.
|
Click Ok to save the configuration. |
The Port Pair is associated with the selected tags.
To remove tags:
|
1.
|
Select the required Port Pairs that are already associated with tags. |
|
2.
|
Click the Tags drop-down menu button and select Delete. |
|
3.
|
In the Delete Tags from Resources page, select the required Tag Keys and Tag Values that must be removed from Port Pairs. |
|
4.
|
Click Ok to save the configuration. |
|
New
|
Use to create a new Port Pair. Refer to Create Port Pair for detailed information.
