are dropped packets a sign of network problem?
in a xen environment , i see a lot op dropped packets via netstat -i

Is this a sign of network problems, or is it normal to see this kind of numbers? i'm not sure how to interprete the data. is this normal, bad, critical. What are your stats on this?

I guess i have a xen issue of some sort, but not sure what yet

Code:
[root@redhat06 xen]# netstat -i

eql_enslave

eql_enslave(8)						      System Manager's Manual						    eql_enslave(8)

NAME

       eql_enslave - enslave a network interface with a master interface

SYNOPSIS

       eql_enslave <master-name> <slave-name> <estimated-bps>

DESCRIPTION

       eql_enslave enslaves a PPP or SLIP network interface to another, named master interface or eql device.

       The  MTU must match the MTU of your serial line device, otherwise, eql_enslave just fails when it is called. You have also to turn off Van-
       Jacobson compression on your slave devices.

       Once the eql device is configured, it will stay up and running until you shut it down manually or reboot. If you have the eql support  com-
       piled as a module then all you have to do is to remove the module after downing the interface.

       Note that you have to connect to a terminal server capable of doing load balancing or another Linux box to use EQL.

EXAMPLES

       # Client Side EQL Driver Initialization

       ifconfig eql 192.168.1.2 netmask 255.255.255.0 mtu 1500

       eql_enslave eql ppp0 33600

       eql_enslave eql ppp1 14400

       eql_enslave eql ppp2 28800
