Can't trunk from D-Link to Arista

Edit: Thank you to everyone that caught my missing native vlan.

My work has replaced our Cisco switches with Arista switches. Connecting the D-link to the Cisco worked but I can't get me D-link 1210-28MP to connect to my Arista 720XP when trying to trunk.

If I leave VLAN settings as default on the D-Link I can get traffic between the two but when I try the trunking settings on the D-Link it looks like only ARP, LLDP, and OSPF traffic is seen. The connection is from port 18 on the D-link to port 15 on the Arista, copper connection.

D-link settings are:
port 18
VLAN 1 Not a Member
VLAN 44 untagged
VLAN 244 tagged

Arista
interface Ethernet15

description Uplink to Access Switch

load-interval 30

switchport trunk allowed vlan 44,244

switchport mode trunk

spanning-tree portfast edge

Any help?

running a tcpdump on a sub-interface : Arista 7280-TR3

I want to look at some traffic on a sub-interface but cannot get to the device to setup a span port.

It looks like I can run a tcpdump but I'm very nervous about running a tcp-dump on a production unit for obvious reasons.

The sub-interface in question only has minimal traffic, pretty much just protocol traffic so won't be much.

Anyone have much experience running a tcp dump on their production unit? Bad idea or is it okay as long as I take precautions with filtering traffic or making sure it's only running on the sub-interface I want?

thanks!
