multicast forwarding & sleeping ethernet interface #392

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
1. Enable multicast forwarding.
2. See IPTV (igmp, NOT udpxy) from STB or other computer.
3. Turn-off (or sleep) first computer, but don't power-down (link light on 
router must be on).

IGMP is freeze, WiFi is disconnect (SSID is visible, but connection is lost and 
not recoverable).

Turning-on computer or disconnect ethernet cable stabilize situation.

Tunings of WMF (disable/enable) or wireless multicast rate has no effect.

Hardware is RT-N16, connection is static IP.

Firmware revision: RT-N16-1.9.2.7-rtn-r4923.trx

Workarounds (udpxy or STB-port in front of NAT) is not applicable for me and i 
must disconnect ethernet cable before turning computer off =)

Can i tune /etc/igmpproxy.conf for only one IP adress or only one port? This 
setting must be power-independent...

Unfortunately, I can't reproduce the problem. Probably, bug in igmpproxy or/and 
EMF appeared in rare situations.
Is situation the same on older releases - r4772, r4667, etc? On recent night 
snapshot?

Please clarify your connection scheme - are one of computer connected by WiFi? 
OS is windows on problematic computer? Link is 100/1000?
Are you able to telnet on router to check it alive?

About connections:
1. Tv-set (for youtube).
2. STB behind NAT. It works throw igmpproxy.
3. Desktop computer - all troubles is begin when it go to sleeping mode. Not 
windows, ubuntu 12.10. Link/Act light on this port stay blinked with all other 
connected LAN ports (igmpproxy routes traffic to internal switch).
4. By WiFi: 2 smartphones and 1 notebook. On this mode all they see SSID, but 
can't connect to WiFi (no IP address and etc).

Later i'll try to connect notebok to free ethernet port and telnet to router 
and write response. Also, i'll check older releases and night snapshots.

I have alternate path - i need to get 1 untagged vlan and 1 tagged vlan, tagged 
forward to STB and untagged for internet throw NAT, but in this firmware this 
way is not simple =)

Thank you.

UPD: link to provider is 100 MBit/s, link to STB and TV is 100 MBit/s, link to 
problem computer is 1000 MBit/s.

Looks like neither ethernet switch, nor igmpproxy unable to detect link 
termination. We will take a look on this, but there is a chance that problem is 
hardware-related.

Issue caused by PC hibernate/sleep mode what forces link to 10Mbps. Since HW 
switch doesn't support IGMP snooping on LAN ports, it gets flooded with 
multicast.
Possible solutions is:
1. move STB port (behing NAT) to different vlan (with help of nvram or robocfg)
2. add that vlan interface to the same LAN bridge (br0)
3. enable EMF
