Strange infos from "robocfg show"

[lamsao]

I have a T-mobile brand of RT-AC68U router loaded with Merlin firmware ver 367.47. I am planning to configure a private network on LAN port 4 following instructions here http://forums.smallnetbuilder.com/showthread.php?t=14983

However, running "robocfg show" I get this.

================================================

60: vlan60: 0 1 4
61: vlan61: 0t 1 2 5t 7t
62: vlan62: 1t 2 3 7 8u
================================================

Could someone explain what the other vlanXX lines are for? Are there any side effects if I remove them? TIA.

That is from preconfigured LAN - IPTV profile.

I am not familiar with IPTV. I don't use it. In fact, my LAN -IPTV profile is not configured. Just curious and really appreciate if someone would explain what these lines mean

56: vlan56: 0t 2 3 7t
57: vlan57: 3 4t 5t 7 8t
58: vlan58: 0t 1t 2t 4t 5t 8u
59: vlan59: 1 3t 4t 7 8t
60: vlan60: 0 1 4
61: vlan61: 0t 1 2 5t 7t
62: vlan62: 1t 2 3 7 8u

Many thanks,

Known issue with robocfg. I don't have access to the Broadcom technical documentation, so I have no way of knowing how to properly retrieve the configured VLANs.
