Hi, In our network, whenever i try to ping a ip address there is inconsistenet replies, after every 10th ping it times out and replies again, this is very inconsistent. But the network is okay when I ping anywhere else. I have checked ofr the counters, errors on the access layer switch, core layer, everything looks okay. The network is liek this user PC - access layer switch - distribution layer - core layer This Ip address I try to ping is on the FDDI ring in the core layer, its an AS400 Box ANy ideas why htis could happen. thanks Gayathri _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
