The following sections describe troubleshooting related to management VLAN access to the switch.
If you are having problems setting up management access in a network where there are only Layer 2 switch connections to the management station, use the following example to troubleshoot the problem.
Three switches, which form three VLANs, are interconnected to a fourth core switch. Network administrators who are connected to one switch need to be able to access all switches. The VLAN port memberships should be set up as shown in the following figure.
In the preceding figure, the management VLAN is VID 2 and all inter-switch ports are configured as tagged ports. The ports that interconnect the switches must be configured as members of the management VLAN, and the management station must be connected to a port that is also a member of the same VLAN.
For management VLAN access, ensure that:
If you are having problems setting up management access in a network where there are Layer 3 switch connections to the management station, use the following example to troubleshoot the problem.
Three Layer 2 switches, which form three VLANs, are interconnected to a fourth Layer 3 switch. Network administrators who are connected to one Layer 2 switch need to be able to access all switches for management. The VLAN port memberships should be set up as shown in the following figure.
In the preceding figure, the management VLAN is different on each switch, with the Layer 3 switch interconnecting the VLANs. The ports that interconnect the switches are configured as tagged ports. The ports on the Layer 3 switch that connect to the other switches must be configured as members of the management VLAN for each switch.
For management VLAN access, ensure that:
The switch contains two firmware components that can be upgraded: the diagnostics (or Boot-ROM) code and the runtime operation code. You can upgrade the runtime code through the switch's RS-232 serial console port, through a network connection to a Trivial File Transfer Protocol (TFTP) server, or with SNMP management software. You can upgrade the diagnostics code only through the switch's RS-232 serial console port.
|
NOTICE: Use the switch's web interface to download the runtime code through TFTP (see "Firmware Upgrade"). Downloading large runtime code files through TFTP is normally much faster than downloading files through the switch's serial port. |
You can upgrade switch firmware by connecting a computer directly to the serial console port on the switch's front panel and using VT100 terminal emulation software that supports the XModem protocol. (See "Connecting the Console Port.")

You can store up to two runtime and two diagnostic code files in the switch's flash memory. Use the [D]elete File command to remove a runtime or diagnostic file that is not set as the startup file (the S/Up setting for the file is 0).
If you are using Windows HyperTerminal, click Transfer and then click Send File. Select the XModem Protocol and use the Browse button to find the required firmware code file on your computer.
The Xmodem file send window displays the progress of the download procedure.
