UCS Comminication


STP is a protocal which detects from the formation of loops by blocking the ports when they see the same traffic

comming back.This typically happens during boardcast strom.

-----------------------------------------------------------------------------------

IF A blade1 in Chasis 1 connected to port 1 is sending a packet to Blade 2 in chasis 1 port 1 them packet is sent to FI and

switched back again if this is in same Vlan.If the traffic is detianed for outside the FI or another vlan or to a port

on other FI the traffic is sent out an uplink port.

Curretly 6200 are not layer 3 ready but this is going to happen in future.
-----------------------------------------------------------------------------------------------------------------

Traffic recived by the FI for a server is forwarded on  if the traffic arrives on the pinned uplink or port channel.

Reverese  Path forwarding

If traffic is recived on a diffrent uplink than one pinned to the server it is dropped

Deja vu Check
-----------------------------------------------------------------------------------------------------------------


UPlink Config from interconnect to Core Network Switches.

1) Atleast two uplinks from interconnect to Core Network Switches

2) or Use VPC(Virtual port channel  if these are nexsus 7000 series)

3) Configure interface in trunk mode

4) Configure Sapnning tree portfast trunk(So that failover happen faster)

5)Specify Vlans  to trunk

6)CreaTE PORT CHANNELS AND ADD INTERFACES .Port channel must be lacp active mode.

7)uplinked Switches must be trunk vlans to UCS.

8)Use pin gourps for DMZ atleeast UCSM 2.0
