The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Cisco to Netgear Etherchannel config - what's best?

Asked by Sir_Lambalot in Network Switches & Hubs, Network Analysis Software, Network Design & Methodology

Tags: cisco, netgear, switches, etherchannel, aggregated links, LACP

Cisco 3560E -> Netgear GS724TS

On the Cisco switch you can configure the Aggreagate link as ON (Etherchanne), Active (LACP) or Desirable (PAgP - Cisco propietary protocol).

On the Netgear switch you can configure 'Static' or 'LACP'

I have configured 2 interface Aggregate links between the Cisco switch & Netgear switch.  I have tried 'Static' (NG) & Etherchannel (Cisco)

interface GigabitEthernet0/9
 switchport access vlan 103
 switchport mode access
 channel-group 9 mode on

& 'LACP' (NG) & Active (Cisco)

interface GigabitEthernet0/17
 switchport access vlan 106
 switchport mode access
 channel-protocol lacp
 channel-group 3 mode active

I am not 100% sure that this is the issue, but every 1000 minutes the Netgear switch becomes unpingable from our monitor server (& from elsewhere in the network).  All 7 GS724TS switches are on their own exactly 1000 minute cycle & I think maybe the Aggreagate link config may mean that the Aggregate links are unstable (NB the switches till pass traffic, just they cannot be pinged).

Does anyone else have an Aggregate link configured between a Cisco device & a Netgear device, ideally specifically a Cisco 3560E & a Netgear GS724TS (or GS748TS) & can you recommend the correct config?  Anyone experienced a similar issue?

As mentioned, not 100% sure it is the LAGs - may be something else.  I have a Netgear GS724T configured & connected exactly the same as the GS724TS & it does not alarm every 1000 mins!

Many thanks in advance,

Simon
