What is the use of the "admin" settings in LAG configuration of the JGS524Ev2?
I just received my new switch and tried to configure the LAG with my various QNAP...
My current config is done setting up one LAG per QNAP, selecting the ports I set up for each of my QNAP (so I have port 1,2 linked to LAG ID 1, and port 3,4 linked to LAG id 2)...
On the qnap side, in port trinking, I've selected adaptive load balancing.
Now here are my questions :
- What would happen if I didn't configure any LAG on the prosafe side?
- what is the use of the admin mode (which seem to break things if I enable it)? what are the differences between active and inactive admin mode?
- if the JGS524 doesn't use 802.3ad, what protocol does it actually implement with the LAG ?? what is the actual use case of this feature?
Knowing the answer to those first questions, I should be able to answer my second level questions, among which "what would be the best configuration on each side, in the case (my case) where I have N users using the QNAPs for watching videos, talink to sql databases, while the QNAP are downloading data from the internet? (So I have incoming connections from various local MACs, and outgoing connections through a static gateway)?" and adapt my use of the GS to the max of it's hability..
Re: What is the use of the "admin" settings in LAG configuration of the GS524?
Welcome to the community!
Kindly read below:
a. What would happen if I didn't configure any LAG on the ProSAFE side?
ANSWER: Even though you have configured LAG on the JGS524Ev2 switch, it will not work with the QNAP because the switch only supports static LAG and it does not match the adaptive load balancing you've set on the QNAP.
b. What is the use of the admin mode (which seem to break things if I enable it)? What are the differences between active and inactive admin mode?
ANSWER: If the admin mode is enabled, it means that traffic will flow. On the other hand, if the admin mode is disabled, there is no traffic at all.
c. If the JGS524 doesn't use 802.3ad, what protocol does it actually implement with the LAG ? What is the actual use case of this feature?
ANSWER: The JGS524Ev2 switch supports the IEEE 802.3ad standard, however, it only supports static LAG which is an early release of the IEEE 802.3ad standard.
Let me ask you, is there an option for static LAG on the QNAP? I believe static LAG is same as Balance XOR (IEEE 802.3ad draft v1) or sometimes called Round-Robin (found out this info from a community member, here is the link). If ever there is a static LAG option, kindly select that and it should work with the JGS524Ev2.
If ever there is no option for static LAG on the QNAP, what you need is a switch that supports LACP (Link Aggregation Control Protocol) which is a subcomponent of the IEEE 802.3ad standard.
You might want to check on NETGEAR Smart switches that support LACP like the GS110TP and XS712T. Here are their data sheets below respectively:
Furthermore, let me share this forum link. The community member had stated there that he configured LACP on the XS712T switch and IEEE 802.3ad (LACP) on the QNAP and it works.
