root@juniper-lab# show vlans map
vlan-id 3;
interface {

I see the mac address too.
I had an defective ethernet on the last test PC . I verified this PC, when I connect to a normal access port on both switches , it works . From the packet captures , I dont see the ICMP entering the ingress interface ge0/0/2
On the PC1 , I see the arp entry for
MacBook-Pro:~ PC1$ arp -a
? (10.10.11.2) at e4:b9:7a:51:aa:29 on en0 ifscope [ethernet]
or the ping from other PC2.
On PC2, I dont see the arp entry on the machine
I dont see arp entry for PC1
