OfficeConnect HPE 1920S-48 - Changing Management VLAN

[id1974]

Hello,

I have recently purchased a few of these to be added to an existing network. The current network switches have VLAN 20 setup on them, and the Management IP in the 10.0.20.x range.

For these new HPE switches, I can't seem to figure out a way through the web interface, to correctly change this management VLAN.

Steps I've done:
1) Created VLANS of 20, 200
2) Assigned Ports 4-24 to VLAN 20 and 25-46 to VLAN 200
3) Assigned Port 1-3 to the default VLAN 1

We would like to be able to manage this swtich via the Management IP, from any system connected to any of the VLAN 20 Ports, but seem unable to do so. Whenever I try to change the management VLAN to 20, the webpage returns an error, and then the configuration never saves.

The web management page works fine from VLAN 1, Port 1, but as soon as I try to change it to anything else, it fails to update.

Thank you in advance for any assistance.

After changing the Management VLAN ID and selecting a Management port, have you tried connecting a PC directly to that management port and tried to access the switch.

Below is the additional information about Management VLAN ID and Management port for this product.

Management VLAN ID

Access to the management software is controlled by the assignment of a management VLAN
ID. Only ports that are members of the management VLAN allow access to the management
software.  By default, the management VLAN ID is 1. The management VLAN can be any value
between 1 and 4093. All ports are members of VLAN 1 by default; the administrator may want
to create a different VLAN to assign as the management VLAN and associate it with a
management port (see the next field).
A VLAN that does not have any member ports (either tagged or untagged) cannot be
configured as the management VLAN.
When the network protocol is configured to be DHCP, any change in the configured
management VLAN ID may cause disruption in connectivity because the switch acquires a
new IP address when the management subnet is changed. To reconnect to the switch, the
user must determine the new IP address by viewing the log on the DHCP server.

Management Port

Access to the management software can also be controlled by the selection of a management
port. The selected management port is auto-configured to be an untagged member of the
management VLAN and is excluded from any other untagged VLANs.
When the switch boots with the default configuration, any port can be used as management
port and this field is configured as None.
You can configure a management port to ensure that a port always remains an untagged
member of the configured management VLAN; this helps to ensure management connectivity
in case of an accidental change in VLAN membership.
If no management port is specified, then all ports that are members of the management VLAN
provide access to the switch management interface. If a management port is configured,
access to the switch is restricted to that port. For example, if VLAN 1 is the management
VLAN and port 10 is the management port, other ports that are members of VLAN 1 will not
provide access to the switch management interface.
The features that utilize the management port include the following:
· DHCP
· SNMP
· SNTP
· TFTP

Click Apply to update the switch configuration. Your changes take effect immediately but are not retained across a switch reset unless you click Save Configuration.

Note: Changing the management port from the default configuration not only restricts access to the web UI
but also impacts the following protocols: DHCP, SNMP, SNTP, and TFTP.
