Manage 2 swtiches summit x440

meinguer — Sat, 24 Oct 2020 23:57:51 GMT

Hello! I´m new in the communty so if the tittle or the tags are wrong an apoligize and I really appreciate that you can tell me in order to change it

I´m have my sw in production, and everything works fine with the vlans and the traffic the only probIem is that I don´t really know to manage my switches, i already put an ip to my sw but i cannot ping them,i have several extreme swtiches, and this are the models X440-24x-10G, Summit X440-48t, Summit X440-L2-48t.

In the Sw core (x440-24x-10G) i have my vlans with ip, and i have the default vlan with this configuration,

configure vlan Default ipaddress 172.23.10.250 255.255.255.0
enable ipforwarding vlan Default

configure vlan Default add ports 1 tagged
configure vlan Default add ports 2-7,19,21-22 untagged

In my sw X440-48t

configure vlan Default ipaddress 172.23.10.53 255.255.255.0
enable ipforwarding vlan Default

configure vlan Default add ports 47-48 tagged

I see that i don´t tag the port of the conection in my sw Core, the conection in my x440-24x-10G is the port 7, and in the sw w X440-48t is the port 47

meinguer,

on the X440-48t:

configure vlan Default add ports 47 untagged

enable port 47

ont eh x440-24x-10G:

enable port 7

to check if you see the other mac on the core:

show fdb port 7

Thanks for the reply, I´ll do it, but i just have one doubt, shouldn´t the port has to be taggeed? is the trunk port, between this 2 switches..

Hi,

The links having the same VLAN tagged on one side and untagged on the other is definitely problematic.

On the 24 port switch can you run the following command and see if you the IP address of the 48 port(.53)

show iparp 172.23.10.53

Thanks,

Chris Thompson

meinguer,

That depend on what you want to achieve

If you want to tag it type this on the core:

configure vlan Default add ports 7 tagged

I did that but no, I cannot see it, I run the show iparp port 7 and just send me the IP's of my computers but nothing about the IP of the SW, and I just run the command as you recommend me and this is what shows
