Test Case 12 - Simulate Port Failure On Pc; Test Case 13 - Simulate Smlt-Srx Port Link Failover - Avaya VSP 9000 Technical Configuration Manual

5.12 Test Case 12 – Simulate Port Failure on PC
The objective of this test case is to simulate port failure (on the PC) while sending traffic and then validate
that data continues to run on the remaining port.
Test Steps
1) Start Vdbench.
2) Make sure SMLT/MLT is
functioning.
Send Layer 2 traffic to populate
MAC tables on all switches.
Remove port p1 from each PC.
3) Verify that I/O continues from PC
to SRX and MAC addresses are
learned properly.
5.13 Test Case 13 – Simulate SMLT-SRX Port Link
Failover
The objective of this test case is to simulate an SRX port link failover.
Test Steps
1) Start Vdbench.
2) Make sure SMLT/MLT is
functioning.
Remove port p1 from the SRX.
Wait 2 minutes and plug the port
back in.
3) Verify that I/O continues from PC
to SRX.
Avaya VSP 9000 / Avaya VSP 7000 with Coraid EtherDrive SRX-Series
August 2011
Expected Results
I/O traffic should flow normally but at a
slower throughput because one port is
down.
Check the VSP 7000/9000 MAC table
and port statistics to make sure traffic
is forwarding and MAC is learning
properly.
Expected Results
I/O traffic should flow normally but at a
slower throughput because one port is
down.
Coraid driver takes 80-100 seconds to
detect and mark the link as down.
After the link is plugged back in, it
takes 8-10 secs for I/O traffic to
resume on that link. The downed link
that came back up had to re-initialize
and do SAN disk discovery before I/O
traffic starts flowing again.
Test observation – If you unplug a link
and plug it back in quickly (1-2 secs),
I/O traffic resumes on that link sub-
second since the link is not yet
marked down by the Coraid driver.
Vdbench should finish with no errors
in the log file and all data should be
validated.
