Hi,
Below is the config of virtual, pool and snatpool on F5 that is in production. need assitance.
snatpool vlan12_sp { member 63.25.36.7 }
pool reversenpath_vlan12_pl { member 63.25.36.1:any }
virtual reversenpath_vlan20_vs {
snatpool vlan12_sp
pool reversenpath_vlan25_pl
destination any:any
mask 0.0.0.0
profiles fastl4_reversenpath_default {}
vlans 20 enable
Internet is not working on the servers connected to vlan 20.

genseek_32178So what then is the used of the below pool, mapped to the wild card VS.

So what then is the used of the below pool, mapped to the wild card VS.
pool reversenpath_vlan12_pl { member 63.25.36.1:any } bigip will send traffic to destination address via pool member address (using pool member as gateway).- genseek_32178in the below tcpdump command, i want to capture only 100 packets. what is the switch to be inserted?
tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap host x.x.x.x or host 63.25.36.7 - nitass-c Exit after receiving count packets.

Following pool and monitor is configured, as can be seen below.
pool asm_443_pl {
monitor all https_asm_mn
members {
172.20.60.10:https {}
172.20.60.12:https {
down
}
172.20.60.25:https {
down
monitor https_asm_mn {
defaults from https_default
dest *:https
send "Get /HeartBeat/Probe.html HTTP/1.0\r\n\r\n"
As can be seen, few nodes in the pool are showing down and few UP. Any thoughts - nitassAs can be seen, few nodes in the pool are showing down and few UP. Any thoughtsAaron has written very good health monitor troubleshooting guide.

tcpdump -r/var/tmp/output.pcap to read the file at the command line. To copy to a different machine, you can use scp or pscp
pscp root@:/var/tmp/output.pcap . - nitassthanks Jason!
