Can anyone tell me what the output of IPARP means? I am unable to contact one of my vlans from outside of the switch. In other words, if I ping a device at IP 188.8.131.52 on vlan 800 from the core switch (an x670), I get a response. If I attempt to ping it from a host on another vlan, which means the x670 should be routing between the two, I can't get a response. These networks are all directly connected so no routing protocol is in use.
I did iparp vlan and saw the following:
* Slot-1 CORE # show iparp "vlan100"

The portion that caught my attention was the "rejected IP" section (which is the IP of the device I'm trying to ping), and the "rejected I/F" which is actually a different vlan from the one the device I'm pinging belongs to. Could this be related at all to why I can't get to that device?
Please note, I have at least 5 other vlans set up in the same manner and am having no issues reaching them at the moment, so it seems to be specific to this vlan.
Thanks in advance. (from transient1)
