Managing Serviceguard Eighteenth Edition, September 2010

cmviewcl -v -f line will report the same failure like this:
node:gary|interface:lan2|status=down
node:gary|interface:lan2|disabled=false
node:gary|interface:lan2|failure_type=link+ip
If local switching is not configured and a failure is detected by IP monitoring, output
from cmviewcl -v will look like something like this:
Network_Parameters:
INTERFACE STATUS PATH NAME
PRIMARY down (IP only) 0/3/1/0 lan2
PRIMARY up 0/5/1/0 lan3
cmviewcl -v -f line will report the same failure like this:
node:gary|interface:lan2|status=down
node:gary|interface:lan2|disabled=false
node:gary|interface:lan2|failure_type=ip_only
Automatic Port Aggregation
Serviceguard supports the use of automatic port aggregation through HP-APA
(Auto-Port Aggregation, HP product J4240AA). HP-APA is a networking technology
that aggregates multiple physical Fast Ethernet or multiple physical Gigabit Ethernet
ports into a logical link aggregate. HP-APA allows a flexible, scalable bandwidth based
on multiple 100 Mbps Fast Ethernet links or multiple 1 Gbps Ethernet links (or 200
Mbps and 2 Gbps full duplex respectively). Its other benefits include load balancing
between physical links, automatic fault detection, and recovery for environments which
require high availability. Port aggregation capability is sometimes referred to as link
aggregation or trunking. APA is also supported on dual-stack kernel.
Once enabled, each link aggregate can be viewed as a single logical link of multiple
physical ports with only one IP and MAC address. HP-APA can aggregate up to 32
physical ports into one link aggregate; the number of link aggregates allowed per
system is 50. Empty link aggregates will have zero MAC addresses.
You can aggregate the ports within a multi-ported networking card. Alternatively, you
can aggregate ports from different cards. Figure 3-19 shows two examples.
