We have two 6509's with MSFC1's. We are running HSRP between the two MSFC's. Both are running 12.1.11 IOS. There is also a 7206 that connects the network to a T3 link through an LS1010. Between the 7206 and the 6509's is a PIX 515.
On both the MSFC's and the 7206, the TTY Background process is high, causing the CPU to be high.

CPU utilization for five seconds: 28%/2%; one minute: 28%; five minutes: 28%

It could be due processes that are initiated from a tty (such as debug, show tech, etc), in addition to general tty maintenance and monitoring. Also see if there is any device connected to the console port
For the most part this might spike high (and we will allow it to take alot of CPU
cycles if the router isn't doing much), but otherwise it should be pretty low
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
