Just trying to run a debug packet capture on the following:
Stack of 4 x X450G2-48P-10G4, running version 188.8.131.52-patch1-4
As per the following GTAC articles:
(This article is slightly wrong in that I had to use 'ports' not 'port' as shown.
Have tried the following commands:
debug packet capture ports 1:21 on vlan B20_23-L-GND-Voice cmd-args "-c 1000"
debug packet capture ports 1:21 on count 1000
These both take OK but the only file produced in the /usr/local/tmp is a file called capture.log
When I look at that file capture.log it contains the following:
tcpdump: can't add port 10015 on packet socket: Protocol not available
Maybe there is some restriction, perhaps on a stack, model or version that is causing that issue that I've missed?
Appreciate any help in advance.
