Hi:

Interface doesn't list all filters, but only show up in alternating order.

# Set ipv4 firewall filter to interface ae1
=====================
set firewall family inet filter ip4_sample term t1 then count ip4_sampling_count
set firewall family inet filter ip4_sample term t1 then sample
set interfaces ae1 unit 0 family inet filter input ip4_sample
set interfaces ae1 unit 0 family inet filter output ip4_sample
set forwarding-options sampling input rate 10  
set forwarding-options sampling family inet output flow-server 192.168.0.1 port 1000

# Set ipv6 firewall filter to interface ae1
—————————————
set firewall family inet6 filter ip6_sampling term t1 then count ip6_sampling_count
set firewall family inet6 filter ip6_sampling term t1 then sample
set forwarding-options sampling input rate 2000
set forwarding-options sampling family inet6 output flow-server 192.168.0.2 port 1000 version9 template v6
set forwarding-options sampling family inet6 output inline-jflow source-address 1.1.1.1
set services flow-monitoring version9 template v6 ipv6-template
set interfaces ae1 unit 0 family inet6 filter input ip6_sampling
set interfaces ae1 unit 0 family inet6 filter output ip6_sampling

When I do a "run show interface ae1 detail"; only 1 filter is shown up at a time instead of 2 filters shown up on interface "ae1".
That is, filter "ip4_sample" was shown first, then about 10 seconds - 2 minutes later, "ip6_sampling" filter would be shown next; continued in this alternating fashion. Is that expected behaviour?

admin@mx960# run show interfaces ae1 detail
.........
Input Filters: ip4_sample
Output Filters: ip4_sample

admin@mx960# run show interfaces ae1 detail
.........
Input Filters: ip6_sampling
Output Filters: ip6_sampling

Hello PL2,

Greeting!

I have dumped the same configuration on one of the lab devices and I was able to see both filters.  IPv4 sample and IPv6 Sampling.

labroot@re0> show version
Hostname: jtac-mx480-r2032-re0
Model: mx480
Junos: 19.1R1-S4.2

[edit firewall family inet]
labroot@re0# show
filter ip4_sample {
term t1 {
then {
count ip4_sampling_count;
sample;
}
}
}

[edit firewall family inet6]
labroot@re0# show
filter ip6_sampling {
term t1 {
then {
count ip6_sampling_count;
sample;
}
}
}

[edit forwarding-options sampling]
labroot@re0# show
input {
rate 2000;
}
family inet {
output {
flow-server 192.168.0.1 {
port 1000;
}
}
}
family inet6 {
output {
flow-server 192.168.0.2 {
port 1000;
version9 {
template {
v6;
}
}
}
inline-jflow {
source-address 1.1.1.1;
}
}
}

[edit interfaces ae0]
labroot@re0# show
aggregated-ether-options {
lacp {
active;
}
}
unit 0 {
family inet {
filter {
input ip4_sample;
output ip4_sample;
}
address 1.1.1.1/32;
}
family inet6 {
filter {
input ip6_sampling;
output ip6_sampling;
}
}
}

---------------------------------------------------------------------------------------------

Each iteration was taken after 30-40 seconds after the previous one:

labroot@re0# run show interfaces ae0 detail |match filters

Output Filters: ip4_sample
Input Filters: ip6_sampling

Can you please tell me which version you are seeing the issue and on which device?

I hope this helps. Please mark this post "Accept as solution" if this answers your query.

Kudos are always appreciated!

Sorry, both filters were there the whole time. I just missed seeing one of them.

Hello Pl2,

Thanks for the confirmation. 

Request you to mark the solution for the queries you post as accepted if it answered your query/queries.

This would enable others to find the right solution for the same/similar queries on the forum.

I hope this helps. Please mark my above post "Accept as solution" if that answers your query.

This doesn't look to be expected behavior. What platform and junos are you running? You may want to open a JTAC case to check if there's any underlaying issue or just simple display/cosmetic issue
