Hi Gareth,
we have C5210 with v.10.41.10.014 and APs 38xx/39xx with same version, but we don't have iperf inside APs:
/usr/bin
M90# ls
dbclient dropbearkey iked pmap rpcapd sftp-server vmstat
dropbear dropbearmulti ntpclient ps2 scp utcpdump
M90# iperf3
-sh: iperf3: not found
Any Idea??
Thanks a lot
