Hello Dina. There are a number of things to consider. (what kind of bond mode, how many interfaces in the bond, etc..) Assuming you created bond0, can you provide the output from the following:
cd /etc/sysconfig/network-scripts
cat ifcfg-bond0
egrep 'MASTER|SLAVE' ifcfg-*
cat /proc/net/bonding/bond0
service NetworkManager status
Also - plesae review:

Potential issues:
one of the interfaces in your bond is not in the correct VLAN
there can be a delay when the bond first comes up
there are no slaves in your bond
You can attempt to monitor traffic on both physical interfaces (individually) using tcpdump to confirm you are seeing traffic on the VLAN you would expect
tcpdump -i em1
Unfortunately a delay in starting a bond is fairly typical (but not usually something that is not acceptable). I generally attach my bond to a bridge.
