Can it be provided? My unit only has a sticker present for the WAN port. ## Answer Both MAC addresses can be seen from the web interface in Advanced Options / View Network Diagnostics. Look in the "Address Information" section. Here's an example from my unit. "eth0" is the LAN port (IP set to 192.168.2.64) and "usb0" is the WAN port, (IP set to 192.168.0.180): -- Address information 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: dummy0: mtu 1500 qdisc noop state DOWN group default link/ether 42:f5:0c:6b:98:03 brd ff:ff:ff:ff:ff:ff 3: eth0: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:13:95:07:f2:d3 brd ff:ff:ff:ff:ff:ff inet 192.168.2.64/24 brd 192.168.2.255 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::213:95ff:fe07:f2d3/64 scope link valid_lft forever preferred_lft forever 4: sit0@NONE: mtu 1480 qdisc noop state DOWN group default link/sit 0.0.0.0 brd 0.0.0.0 5: usb0: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:50:c2:13:90:82 brd ff:ff:ff:ff:ff:ff inet 192.168.0.180/24 brd 192.168.0.255 scope global usb0 valid_lft forever preferred_lft forever inet6 fe80::250:c2ff:fe13:9082/64 scope link valid_lft forever preferred_lft forever ## Let us know how we can help If you have further questions on this topic or have ideas about improving this document, please [contact us](https://www.telosalliance.com/support-request).
