A 0 byte udp packet sent to SNMP port
(nmap -sU -p 161 pont-vesale) crashes the bridge.

nef:~$ snmpwalk pv public system
system.sysDescr.0 = "ScorpionMarlin"
system.sysObjectID.0 = OID: enterprises.541.1
system.sysUpTime.0 = Timeticks: (130641320) 15 days, 2:53:33.20
system.sysContact.0 = "NoContact"
system.sysName.0 = "PONT-VESALE"
system.sysLocation.0 = "NoLocation"
system.sysServices.0 = 15

nmap documentation extract:
       -sU    UDP scans: This method is used to  determine  which
              UDP  (User  Datagram  Protocol,  RFC 768) ports are
              open on a host.  The technique is to  send  0  byte
              udp packets to each port on the target machine.  If
              we receive an ICMP port unreachable  message,  then
              the  port  is  closed.   Otherwise  we assume it is
              open.
