Multicast Router - Management
Configuration and Management Features
ZYTRAX Routers provide a number of management features.
Router configured using SNMP and a
ZyTrax Enterprise MIB.
ZYTRAX Routers are configured
using a ZyTrax enterprise SNMP MIB. The MIB allows read access using a community
value of 'public'. Write access requires a unique 'community value'
(password).
SNMP support for standard IP, UDP,
TCP, ICMP, and Interface statistics.
Standard MIB-II values for TCP, IP, UDP, ICMP and the Interface group can be read via the Router.
Telnet support for run-time
diagnostics and statistics.
Telnet is
supported for read only purposes and has 16 pages of diagnostic and status
information available including interface stats, IP. UDP, TCP, ICMP stats,
Link connection status, monitor of traffic going into and out of the
router (by IP source and destination address) etc.
Software controlled reset feature (via
TCP, UDP or ICMP).
WarpOne may be
reset locally or remotely using either TCP, UDP (via the MIB) or ICMP (all
methods subject to Access Controls).
Full Local and remote management and
diagnostic support.
All WarpTwo management and diagnostic features may be run remotely or locally. When using remote management services with a thin Proxy service a Port Map must be defined to enable the required access methods.
LIVE MIB feature allows the user to dynamically
change configuration at run time (without service interruption).
WarpTwo supports a LIVE MIB service. When a SNMP enterprise MIB parameters is changes the configuration will be immediately used i operation running. This allows live re-configuration of all router features without incurring any down-time.
Access Lists (GoodGuys) define
allowable management and diagnostic features on a per IP address (and optional
subnet mask) basis.
The GoodGuys list (a.k.a an Access List) defines those Hosts (or Host ranges) that are permitted access to Router features. The access list may be further defined to
allow access to any or any combination of features (Configuration, Monitoring
and Reset/Load). In low security environments a Telnet password is used to deter
and stop accidental access to the router.
Dual applications maintained in FLASH
memory.
WarpTwo maintains two copies of the application in FLASH. One of these copies is
LIVE (being used), the other is available to be upgraded. This method
ensures that it is impossible to lose the application even if power fails
during an application update cycle. Many competing products die under
these circumstances or require additional analog line access.
Application upgrades may be ‘downloaded’
and written to FLASH during normal operation.
WarpTwo maintains two copies of the application in FLASH. One these copies is LIVE
(being used), the other is available to be upgraded. This method allows an
application upgrade to be treated like normal data transmission and
without interrupting normal routing functions. To use the new application
the router must be reset. A special MIB parameter is used to allow a
number of seconds to be defined after which the router will reset. Thus a
new application can be loaded during the day and the router configured to
reset at 2 AM in the morning.
Dual FLASH applications and unique
'probation' feature ensures that the most reliable software is always
operational.
ZYTRAX Routers maintain two
copies of the application in FLASH. When a new application is loaded it goes
onto 'probation'. If the new application fails before it has exceeded the time
that the previous version was running for, the router reverts to the previous
application after the reset. This ensures that the most ereliable version of the
application is always active. This feature can be overridden using a MIB
parameter if required.
