vlan interface question

vlan interface question

Can I assign the same vlan interface to different extreme? Based on the definition of what a VLAN is, I think I can, but my boss thinks not. We had a big argument with him, please tell me friends. I assigned and everything worked fine for me, because of him I removed them, and I cannot search for devices on the ARP table. You have to look for the FDB table, which is extremely time consuming

ok, thank you so much.
create vlan printers tag 10
configure vlan printers ipaddress 10.1.10.1/23
configure vlan printers add ports 12 untagged

create vlan printers tag 10
configure vlan printers ipaddress 10.1.10.1/23
configure vlan printers add ports 11

or

switch 1
create vlan printers tag 10
configure vlan printers ipaddress 10.1.10.1/23
configure vlan printers add ports 11 untagged
configure vlan printers add ports 24 tagged
switch 2
create vlan printers tag 10
configure vlan printers ipaddress 10.1.10.2/23
configure vlan printers add ports 12 untagged
configure vlan printers add ports 24 tagged

In this case, no - you should not be using the same IP address on each switch. Connecting to that IP will yield unreliable results as both IP's will respond to the same ARP requests and during initialization (when a gratuitous arp is sent, one will likely back off seeing that another device shares that IP). It probably works for what you described (seeing IP's associated with other devices), as that information is pulled from broadcast traffic, but those IP's should be independent to allow for management, proper ARP cache for end stations, etc.

look
(Switch 1 and switch 2 are connected to each other on port 24 each. End devices (printers) on port 11 on the first switch and port 12 on the second switch.)
switch 1
create vlan printers tag 10
configure vlan printers ipaddress 10.1.10.1/23
configure vlan printers add ports 11 untagged
configure vlan printers add ports 24 tagged
switch 2
create vlan printers tag 10
configure vlan printers ipaddress 10.1.10.1/23
configure vlan printers add ports 12 untagged
configure vlan printers add ports 24 tagged.

I wrote everything correctly?

Please post a quick diagram of your layout as I think we might be misunderstanding each other.
