IEEE 802.3ad Connection Issues

[mikew654321]

Hello,

I recently purchased a cisco 300 series 10 port managed switch and a synology 1511+ diskstation.  When trying to bond the 2 ethenet ports into link aggregation mode on the diskstation, i am recieveing an error that's "failing to establish IEEE 802.3ad connection".

From what i understand, the switch should allow this by defealt, but i am unable to determine why it's not allowing it.

If anyone could please help, it would be greatly apprechiated.  I am rather new to cisco gear.

Thanks!

Michael

Hello,

Have you solved your problem?

I have the same issues with you except I'm using SG200-18 with Synology 1512+.

Hello Mike Watts, can you provide the LAG configuration you've placed on the switch?

A lot of times the NAS will only support a LACP (not static LAG). However, if you can provide what kind of LAG the NAS will support will be most helpful.

From the command line here would be a sample input using LACP;

configure terminal

interface range fastethernet 3-4

channel-group 1 mode auto

From the command line here would be a sample input without using LACP;

configure terminal

interface range fastethernet 3-4

channel-group 1 mode on

This will make a lag for port 3 and 4.

Please let me know if this helps at all.
