I have two lacp bonds configured on my linux box, identical to each other. One is on an iscsi vlan, the other on my access vlan.
The iscsi bond looks fine:

but the access bond is funny in that it shows Number of ports: 1

From both the host and the switch side, both bonds are configured identically:
# cat /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
DEFROUTE=yes
IPV6INIT=no

PEERDNS=yes
PEERROUTES=yes
IPADDR=10.1.11.60
NETMASK=255.255.255.0
GATEWAY=10.1.11.1
BONDING_OPTS=mode=4 miimon=100 xmit_hash_policy=layer3+4
# cat /etc/sysconfig/network-scripts/ifcfg-bond1

NETMASK=255.255.255.0
MTU=9000
BONDING_OPTS="mode=4 miimon=100 xmit_hash_policy=layer3+4"
and from the switch side, it looks fine

So - why is the host showing Number of ports: 1 for the access bond?
