CONFIGURING PORTS | CONFIGURING PORT COMMUNICATION SETTINGS
DRAFT
2. Click on the port you want to configure and select the Port Configuration tab.
3. Using the menus, select the port speed, duplex, MDI/MDI-X and mastery (clock master) as required. Auto is
the recommended settings for all but the most critical situations. Setting anything other than Auto limits the
port speed to the value chosen, even if the link partner does not support that speed. Setting Auto will also allow
the link to renegotiate the link if line conditions change or the link partner is swapped (for information on
avoiding duplex mismatch, see the “Avoiding duplex mismatching” section on page 38).
4. Click Review/apply and review the changes you have made, and then click Apply to implement your changes.
Using the CLI to configure port communications
1. Log in to the CLI as Administrator.
2. Select the TAP module you want to configure. Front modules are numbered 1–4 (left to right), and the rear
module is numbered slot 0.
3. Specify the port/link speed. Ports are labelled A–D (left to right). Auto is the default setting and is
recommended for all but the most critical TAP deployments (see the
“Configuring port failsafe and LFP (TAP
mode)” section on page 40
for advice on configuring ports in critical deployments). Auto also allows the link
partners to renegotiate the connection when line conditions change. Valid options for copper ports are: Auto,
10M, 100M or 1G.
4. Specify the port crossover mode, either MDI (normal) or MDI-X (crossover). To connect two ports of the same
configuration (MDI to MDI or MDI-X to MDI-X), an Ethernet crossover cable is needed to cross over the
transmit and receive signals in the cable, so that they are matched at the connector level. Otherwise, you can
select Auto and let the ports themselves detect the required cable connection type and configure the connection
appropriately.
5. Specify a port duplex mode that matches with the link partner, or leave it at the default auto to auto-negotiate
duplex (for information on avoiding duplex mismatch, see the “Avoiding duplex mismatching” section on page
38).
6. Specify port mastery to determine which end of the link is responsible for the synchronization clock. The link
will only work if there is one Master and one Slave. For example, if port pairing AB are operating in TAP mode,
you are advised to force the partner of A to have the same settings as B, and vice versa. In the case of Mastery, is
done be setting A to Forcemaster and B to Forceslave (or the opposite). If the same ports are in operating in
non-TAP mode, you are advised to set the ports to either Preferslave or Prefermaster, but not to Forceslave.
