10.4.3 Troubleshooting the Routing Table
When adding a new static routing rule, the added rule passes a validation test. If errors are
found, the routing rule is rejected and is not added to the IP Routing table. Failed routing
validations may result in limited connectivity (or no connectivity) to the destinations
specified in the incorrect routing rule. For any error found in the Routing table or failure to
configure a routing rule, the device sends a notification message to the Syslog server
reporting the problem.
Common routing rule configuration errors may include the following:
The IP address specified in the "Gateway" column is unreachable from the interface
specified in the "Interface" column.
The same destination is defined in two different routing rules.
More than 30 routing rules were defined.
Note:
If a routing rule is required to access OAMP applications (for remote
management, for instance) and this route is not configured correctly, the route
is not added and the device is not accessible
connectivity, the device must be accessed locally from the OAMP subnet and
the required routes be configured.
10.5 Configuring QoS Settings
The QoS Settings page is used for configuring the Layer-2 and Layer-3 Quality of Service
(QoS) parameters. DiffServ is an architecture providing different types or levels of service
for IP traffic. DiffServ (according to RFC 2474), prioritizes certain traffic types based on
their priority, thereby, accomplishing a higher-level QoS at the expense of other traffic
types. By prioritizing packets, DiffServ routers can minimize transmission delays for time-
sensitive packets such as VoIP packets.
This page allows you to assign different VLAN priorities (IEEE 802.1p) and Differentiated
Services (DiffServ) to the supported Class of Service (CoS) - Network, Media Premium,
Control Premium, Gold, and Bronze. For a detailed description of the parameters
appearing on this page, see 'Networking Parameters' on page 543. For a description on
QoS and the mapping of each application to a class of service, see 'Quality of Service
Parameters' on page 111.
