i have a 7206VXR NPE-G1 (IOS 12.4(18)) fitted with 2xPA-A3-OC3MM, 1xPA-A3-OC3SMI and 1xPA-A3-E3. I'm terminating DSL customers using Gi0/2 for uplink.
The Gigabit port is simply configured:
interface GigabitEthernet0/2 ip address xxx.xxx.xxx.xxx 255.255.255.252 duplex auto speed auto media-type rj45 negotiation auto
The other end is connected to a Cisco 2960G with identical port configuration.
Sometimes the interface starts to behave badly and output errors counter starts to increase without any apparent reason. If i do a show controller, i see that the errors are due to tx_underflow. What's is strange is that if i cycle down/up any of the ATM interfaces, the problem disappears and come back later (30 mins to 7 hours). I see no errors on the 2960G port. I'm unsure if this could be an IOS bug or a bad hardware, i tried changing port to Gi0/1 but had the same results. Any hint?
Re: Strange problem on NPE-G1 Gigabiteth tx_underflow
To Reza: i haven't tried it yet.. i think that would be my next step
To giuslar: that interface (Gi0/2) carries about 200Mbps IN and 80Mbps OUT in peak traffic times. I have the same setup on a NPE-G2 and never had any problem. I tought about possibly poor performance problems, but since the setup is inside "bandwidth points" limit i hoped that the 7206 could support the traffic. Do you advice me to split the setup adding another 7206?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
