Spanning Tree:
Current Spanning Tree Group 1 setting: ON
Turn Spanning Tree Group 1 OFF? [y/n]
The setup tool prompts you to configure VLANs and VLAN tagging for the ports
(Example 4-6). If you want to change settings for VLANs, enter y, or enter n to skip VLAN
configuration. In our case, we defined the VLANs used for our lab, as described in Chapter 3,
“Reference architectures” on page 107.
Example 4-6 VLAN configuration
Port Config:
Will you configure VLANs and VLAN tagging for ports? [y/n]
After deciding if you want to configure the VLANs, you are prompted to configure the Gigabit
Ethernet port flow parameters (Example 4-7).
Example 4-7 Gigabit Ethernet port flow parameters
Gig Link Configuration:
Port Flow Control:
Current Port EXT1 flow control setting: both
Enter new value ["rx"/"tx"/"both"/"none"]:
Enter rx to enable receive flow control, tx for transmit flow control, both to enable both, or
none to turn off flow control for the port. To keep the current setting, press Enter.
If you select a port that has a Gigabit Ethernet connector, you can configure the port auto
negotiation (Example 4-8).
Example 4-8 Port auto negotiation
Port Auto Negotiation:
Current Port EXT1 autonegotiation: on
Enter new value ["on"/"off"]:
Enter on to enable port autonegotiation, off to disable it, or press Enter to keep the current
setting. In our lab configuration, we defined all the ports with the flow control disabled, with
the option set to none, and the autonegotiation to on.
