COMMAND USAGE

If at any time the switch detects STP BPDUs, including Configuration or

Topology Change Notification BPDUs, it will automatically set the selected

interface to forced STP-compatible mode. However, you can also use the

spanning-tree protocol-migration command at any time to manually

re-check the appropriate BPDU format to send on the selected interfaces

(i.e., RSTP or STP-compatible).

EXAMPLE

Console#spanning-tree protocol-migration eth 1/5

Console#

show spanning-tree This command shows the configuration for the common spanning tree

What to do if I cannot connect to Edge-Core ECS3510-28T using Secure Shell?
- K
  Kyle Long DDSAug 10, 2025
  If you're having trouble connecting to your Edge-Core Network Router using Secure Shell (SSH), ensure the SSH server's control parameters are correctly configured on the router, and that your SSH client software is properly configured on your management station. Verify that you've generated both RSA and DSA public keys on the router, exported the key to the SSH client, and enabled the SSH service. Consider trying another SSH client or checking for updates to your current SSH client application. Also, confirm that you've set up an account on the router for each SSH user, including a username, authentication level, and password. If you're using public key authentication, ensure you've imported the client's public key to the router.

How to access the onboard configuration program via a serial port connection on Edge-Core Network Router?
- C
  Corey EricksonAug 20, 2025
  If you cannot access the onboard configuration program of your Edge-Core Network Router via a serial port connection, check that your terminal emulator program is set to VT100 compatible, with 8 data bits, 1 stop bit, no parity, and a baud rate of 115200 bps. Also, make sure you are using the RS-232 null-modem serial cable supplied with the router. If you're using a different cable, ensure it conforms to the pin-out connections provided in the Installation Guide.
