Configuration manual
Bosch Security Systems B.V.
Requirement Standard Settings
Possibility to create
VLANS n.a. VLAN separation is recommended instead of IGMP
snooping, because most switches are unable to
handle the multicast changes in the system. Filtering
multicast data may be necessary for some devices,
such as 100 Mb devices (Sony cameras, TVOne, AMX,
and others).
IGMPv3 IGMPv2
snooping in
hardware IGMPv3 or IGMPv2 snooping. To optimize bandwidth
usage, IGMP snooping can be used. This is useful in
systems with >10 multicast streams, although not
absolutely required. Sufficient performance for
handling a large number of IGMP query responses,
depends on the number of (directly or indirectly)
connected devices to that switch. Hardware support
for IGMP snooping is strongly recommended.
Requirements when
Redundant wiring is
used Standard Settings
RSTP IEEE802.1D-20
04 RSTP is used to allow the creation of loops for
redundancy. The switch must support changing the
following parameters to the listed values:
–
Hello_Time = 9 seconds
– Forwarding_delay = 30 seconds
– Max_age = 22 seconds
Diagnostics
Link Layer discovery IEEE 802.1AB For network diagnoses using Network Docent.
SNMP SNMP For network diagnoses using Network Docent.
Routers
The following minimal requirements apply to routers:
–
1 Gbit or higher Ethernet ports.
– Supports PIM‑DM or Bidirectional PIM.
– Performs IP routing in hardware (i.e. a ‘layer 3 switch’) to minimize the routing delay.
– Packet forwarding rate > 1,000,000 packets per second per port (e.g. 8 Mpps for an
8‑port router).
– Non-blocking backplane per switching port, i.e. 2 Gbit per port (e.g. 16 Gbps for an
8‑port router).
– MAC address table of at least 1000 addresses per directly connected subnet.
3.2 Network requirements
If the DICENTIS Conference System is being used as a standalone system, it uses the so‑called
dynamic link‑local addresses. This means that the TCP/IPv4 setting of the server PC and client
PCs need to be set to "Obtain an IP address automatically". Normally, these settings are
default and therefore do not require PC network configuration settings.
