Hi All



Can someone help me, I have 2 ExtremeXOS 440 switches version 21.1.1.4 connected to cisco switch 6500.

Problem : when I’ doing continues ping I’m getting packet loss and when one switch responding to my pings another will not respond vice vasa .



This is my configuration on extreme switches

create vlan "internal-man-105"

configure vlan internal-man-105 tag 105

configure vlan internal-man-105 add ports 2:24 tagged

configure vlan internal-man-105 ipaddress 1.1.1.1 255.255.255.248

enable ipforwarding vlan internal-man-105

configure ports 2:24 auto on speed 1000 duplex full



this is my configuration on cisco switch
