I have two Cisco SG550 switches in Core Layer. I have connected this two switches with using Stack Cable.
This two switches uplink connection connected with Access layer switches
When i down the one uplink port connection from one core layer Cisco SG550 switch after that also my data traffic can pass internally fine and via firewall WAN network also working fine
While i am power down one switch and trying to get data traffic from another switch power switch its working
Internal network working fine but Firewall ip address is not reachable i am unable to access WAN
Why this happened
Is that i need to configure any extra Commands, or else what should i do for another switch also get data traffic
please help me to complete my setup
my core layer one switch up link connection is connected with Firewall another switch connection is not connected with firewall - Only one uplink between firewall and Stack able two master switch not with switch
or else i need to give two uplink connection ? between firewall - cisco SG550- Cisco SG550 switch
My topology is as below
cisco SG550 - CIsco SG550 --->Firewall port
switch <---> Switch ----> Firewall ( one uplink connection between switch and firewall )
after power down one switch i am unable to get WAN traffic inside the LAN.
Two switches connected with Stack Cable.
Is that I need to do any configuration or any setup change pls help to complete
judging from your drawing, you only have one physical connection from the SG550 to the Firewall ? If that is the case, powering of any of your SG550 switches will result in the firewall to become unreachable. The purpose of stacking is not to provide redundancy for external connectivity, but rather to ease management, and to expand capacity.
What exactly are you trying to accomplish, a redundant link to the Firewall ?
If i have your topology correct - your core switch(s) even though they are stacked only has one physical connection into the firewall and when that switch drops and the fw port you then dont have any direct path to the firewall.
So you need to either aggregate two ports (one from either switch) into the firewall or just have two access ports connected to the firewall and have one running as a backup to the other
After Configuring LacP Configuration on my cisco SG550 Switch i am getting following Error,
Po1 Active: gi1/0/1 Non-candidate: gi2/0/1
How do i Troubshoot it
My Set up like below
sg550 <----> SG550
