For IOS such as Cat 4500 series do you have to do additional configs such "snmp-server host 10.0.98.43 traps version 3 auth cisco udp-port 162" as other than particular snmp trap notifications you want (e.g. snmp-server enable traps cpu threshold)?   Can anyone give me an example as documents show many variations. ...

I have a 4510 that won't take a "set interface" command as shown in some cisco docs to configure the SL0 or any mgmt ports. Maybe I am doing something wrong. Any help? ... View more

So I have a pair of 4500s joined in a VSS domain. Upon doing testing due to a CLI being slow on any directly connected switch I ssh to from the 4500, I noticed pings will drop every 10-20 or so when doing continuous pings to any one of these directly connected switches or even hosts on those switches. All the switches are Nexus 9k series joined in vPC domains other than the trouble 4500s that I speak of. pings only drop when pinging from 4500 not from other switches.   I did show spanning-tree and it shows my 4500 is the root for all Vlans when it is connected to 9k series Nexus Cores (in a vPC domain) which is the root for all Vlans so I believe i have a loop. What I am trying to figure out is why.    Any ideas? ... View more

I have a 4500 switch in a VSS pair, that when I ssh to other directly connected switches (Nexus 9k in VPC pairs) from it the CLI is very slow meaning takes couple seconds to respond to keyboard commands. On the 2x 4500 VSS pair, I have Po10 on all ports for both devices going to Nexus 9k Core 1 (Po20 on Core1) and Po11 on both 4500s going to Core 2 (Po21 on Core 2). I can't seem to figure out why it may be slow. I see anywhere from 2 to 18 output drops on the port-channel interfaces connecting to the Cores. Also I see the following CPU utilization:   sh processes cpu Core 0: CPU utilization for five seconds: 17%; one minute: 19%; five minutes: 20% Core 1: CPU utilization for five seconds: 13%; one minute: 20%; five minutes: 15% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 1 736 821 896 0.00 0.00 0.00 0 init 2 1 88 21 0.00 0.00 0.00 0 kthreadd 3 117 16859 6 0.00 0.00 0.00 0

So I have just 2x 4500 switches in VSS.   So I read that I can use a port from a Supervisor module and a port on a normal line card for VSL links. I assume I can still use 2 ports on each SUP (on each switch) in addition to using more ports on the normal line cards as part of the VLS links (Port-channel 100 and 101 in this case) meaning no amount of port restrictions correct?   Also, if the end user hosts will only be single homed, is it still ok to run these switches in VSS as would not want issues with saturating the VSL links correct?   Also, I understand that ports 3-4 on each sup will be inactive when operating in RPR or redundancy mode. Is there anyway to enable these so I can use these ports as uplinks to Core switches? Reason is that I only have 1 module on each switch capable of 10GB. ... View more
