# Graphing the IP tab using EDM

Use this procedure to graph information about the IP packets that are interfaced with the switch

## Procedure steps

1. From the navigation tree, double-click Graph.

2. In the Graph tree, double-click Chassis.

3. In the work area, click the IP tab to view the SNMP statistical information.

## Variable definitions

The following table outlines the fields of IP tab.

Field | Description
--- | ---
InReceives | Indicates the total number of input datagrams received from interfaces, including those received in error.
InHdrErrors | Indicates the number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options.
InAddrErrors | Indicates the number of input datagrams discarded because the IP address in the IP header destination field was not a valid address. This count includes invalid addresses (for example, 0.0.0.0) and addresses of unsupported Classes (for example, Class E). For addresses that are not IP Gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address.
ForwDatagrams | Indicates the number of input datagrams for which this entity was not their final IP destination, as a result of which an attempt was made to find a route to forward them to that final destination. For addresses that do not act as IP Gateways, this counter includes only those packets that were Source-Routed by way of this address and had successful Source-Route option processing.
InUnknownProtos | Indicates the number of locally addressed datagrams received successfully but discarded because of an unknown or unsupported protocol.
InDiscards | Indicates the number of input IP datagrams for which no problems were encountered to prevent their continued processing but that were discarded (for example, for lack of buffer space). This counter does not include any datagrams discarded while awaiting reassembly.
InDelivers | Indicates the total number of input datagrams successfully delivered to IP user-protocols (including ICMP).
OutRequests | Indicates the total number of IP datagrams that local IP user-protocols (including ICMP) supplied to IP in requests for transmission. This counter does not include any datagrams counted in ipForwDatagrams.
OutDiscards | Indicates the number of output IP datagrams for which no problem was encountered to prevent their transmission to their destination, but that were discarded (for example, for lack of buffer space). This counter will include datagrams counted in ipForwDatagrams if any such packets met this (discretionary) discard criterion.
OutNoRoutes | Indicates the number of IP datagrams discarded because no route could be found to transmit them to their destination. This counter includes any packets counted in ipForwDatagrams that meet this no-route criterion. This includes any datagrams a host cannot route because all of its default gateways are down.
FragOKs | Indicates the number of IP datagrams that have been successfully fragmented at this entity.
FragFails | Indicates the number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be, for example, because their Don't Fragment flag was set.
FragCreates | Indicates the number of IP datagram fragments that have been generated as a result of fragmentation at this entity.
ReasmReqds | Indicates the number of IP fragments received that needed to be reassembled at this entity.
ReasmOKs | Indicates the number of IP datagrams successfully reassembled.
ReasmFails | Indicates the number of failures detected by the IP reassembly algorithm. This is not necessarily a count of discarded IP fragments because some algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received.
