Fixed In:

Opened: Jun 20, 2016 Severity: 4-Minor
TCL error in /var/log/ltm that looks like 'error Buffer error invoked from within "DIAMETER::avp data get 257 ip4 index 0"'
The iRule ends with an error.
iRule that extracts ip address from a diameter avp.
Instead of set data [DIAMETER::avp data get 257 ip4] use an iRule such as if { [DIAMETER::avp count 257] > 0 } { set data [DIAMETER::avp data get 257] binary scan $data S family switch $family { 1 { # ipv4 should contains 4 bytes set ip [IP::addr parse -ipv4 $data 2] log local0. "ip = $ip" } 2 { # ipv6 should contains 16 bytes set ip [IP::addr parse -ipv6 $data 2] log local0. "ip = $ip" } default { log local0.alert "address family $family is not supported" } } }
DIAMETER::avp data get "id" ip4|ip6 now correctly returns an ip address on valid ip address AVPs.
