Table 19: show ip forwarding-table slot Output Fields
Field Name | Field Description |
|---|---|
Free Memory | Amount of routing table memory free on the line module, in kilobytes |
Virtual Router | Name of the virtual routers configured on the line module |
Memory (KB) | Amount of routing table memory consumed by the virtual router, in kilobytes |
Load Errors | Count of errors made while loading the routing table on the line module Records any failed routing table distribution attempt as an error. Attempts can fail for many reasons during normal operation; a failed attempt does not necessarily indicate a problem. It is normal to see many Load Errors per day. |
Status | Whether the routing table for the virtual router is valid If the Status field does not indicate Valid, then the routing table distribution has failed constantly for that virtual router. It is normal and appropriate behavior for the Status field to indicate Valid while the Load Error field increases daily. |
