I
need to extend the office LAN by connecting an existing CISCO WS-C3750X-12S-S stack to a
new DELL 6248 stack.
I
intend to use the fibre/combo port In DELL 6248 to connect to CISCO uplink
port.
I
want to use DELL port 48 but I saw there were 1/g48 and 1/xg48. From memory, they are mutually exclusive.
Q1. Does it mean I will just configure 1/g48 and
don't bother going into the config of 1/xg48?
Q2. To connect the 2 stacks together, should I
just define both connecting ports as trunk port? I have no experience in doing that. FYI.
We are using VLANs in the CISCO stacks already and so the new DELL
stacks need to know about it.
I
was able to connect the 2 stacks together, but I am not sure if what I did was
correct.
On
the existing CISCO stack, I have been using VLAN 1 as the data (untagged) and
VLAN 100 as voice (tagged).
On
the new DELL stack, I defined 1/g48 (fibre port) as access port and VLAN 100 as
the default untagged VLAN.
On
the existing CISCO stack, I leave the Gigabit 1/0/4 port to its default which
happens to be access mode with 1 as the default VLAN.
I
thought what I did was incorrect but anyway I thought I still gave it a go and
I was able to plug a PC into the DELL stack and do the normal "data"
stuff without any problems.
Q1. So, does it mean that even if the VLAN nos do
not match on the connecting ports, it does not really matter?
Is
this correct?
a)
On the DELL stack, I configured the 1st fibre port as below:
#show
