[f-nsp] Multi Trunking separate VLANs between 2 switches

[Pritesh Patel (CW)]

Trunk id doesn't have to be identical. Can you give me model of devices you are trying to trunk between with their os version?

Thanks,
Pritesh

Hi Pritesh

I built my trunks with the tags and began connecting fiber ports and since that time, the DHCP server wasn't able to respond to voip phones on that network or the phones couldnt reach the DHCP server on the same ip subnet but different switch. This only happened after connecting the trunk fibers.

Do the Trunk IDs for a trunk have to be identical between switches connected trunk groups?

Is it a problem if the IDs match for other Trunks that are not part of the same trunk group on Switch A (NOC main switch)?

Switch A  TrunkBB e3/5 to 3/8 e4/4 to 4/8 ID 67

Switch B TrunkBB e1/4 to 1/8 e 2/4 to 2/8 ID 3



Switch A  TrunkCC e5/5 to 5/8 e6/4 to 6/8 ID 131

Switch C TrunkCC e1/4 to 1/8 e2/4 to 2/8 ID 3


Switch A  TrunkDD e7/5 to 7/8 e8/4 to 8/8 ID 195

Switch D TrunkDD e1/4 to 1/8 e2/4 to 2/8 ID 3



My NOC switch has several unique Trunk IDs however the switch closets all use similar IDs but they define unique trunks which connect to the NOC switch, meaning they are different on each end of the trunk.

No It won't create loop.
You have to tag ports first then create a trunk.

Vlan 10
Tag e 1/5 to 1/8
Vlan 11
Tag e1/5 to 1/8

Then create a trunk group.
Older codes require you to do port /vlan config first before you deploy trunk Then

Trunk ports ..
Deploy

Thanks,
Pritesh

Port typo corrected in group1

SWITCH A TRUNK Group1
e1/1 to 1/4
e2/1 to 2/4

SWITCH B TRUNK Group1
e1/1 to 1/4
e2/1 to 2/4

I can't find an example of multi trunking VLANs between two switches to maximize Group1 and Group2 8GB trunk per vlan. Think this will work? (proper syntax not used) Is the Group2 trunk going to require tagged trunk ports and as a result, carry all the VLANs and then create a loop?

VLAN 1 (default vlan) contains dual mode ports, but trunk shouldn't need dual mode

SWITCH A TRUNK Group1
e1/2 to 1/4
e2/1 to 2/4

SWITCH B TRUNK Group1
e1/2 to 1/4
e2/1 to 2/4


VLAN 2 contains tagged ports and untagged ports and IP Subnet voice traffic

SWITCH A TRUNK Group2
e1/5 to 1/8
e2/5 to 2/8

SWITCH B TRUNK Group2
e1/5 to 1/8
e2/5 to 2/8

Thank you
Gary
