I want to enable SNMP and track the status/ of the interfaces in switches.
We have Two- cat 3750 (L3 switch) and Nine-cat 2960 (L2)
How to configure the SNMP. any Links provides the required info with an example of configuring snmp will be really useful.
we have OPEN NMS, SPLUNK, MYSQL monitoring tools.
i want use CACTI for monitor my bandwidth so i have a question how can i enable snmp for a switch port ? or i shoudl just enable snmp from configuratiopn terminal and then in CACTI i will choose which port will be monitor? can i do something that CACTI connect to my switch with a encryption key ? i have cisco 2960 48 port switch

This release doesnt have the snmp-server enable traps errdisable command.
Where to look on the cisco site for the next available release for me that would have this command in place?
Is there anyway to pull the usernames and passwords from a switch via SNMP or write a new username and password to switch via SNMP. I have switch that was apparently misconfigured and i am not feeling like driving all the way down there to console in.

I am trying to configure a 3750 48 port switch and having trouble with getting it to see the sfp. I just want to set up the router with a pretty basic set up since I am using it for a ping test between 2 buildings, via fiber. How I can enable the sfp port?
View 3 Replies View RelatedI am having a lab switch. Recently I am getting "%SCHED-3-SEMLOCKED: SNMP ENGINE attempted to lock a semaphore, already locked by itself" message and the switch has started to hang a little bit. I just want to know what this log means and how to trouble shoot.
I'm using C3750, version 12.2(25)SEE3
I have a hub and spoke WAN that conisits of one core location with with a 6500 and nine other buildings using 4006 Catalyst that conenct back to the core via dual gig fiber. We are using EIGRP at each location as well as the core. I was tesing something at one of our buildings decided to hang a 3750 off the 4006 and enable the same eigrp process on the 3750 that is enabled on the 4006 and 6500 (EIGRP 1).
1. All the routes that the 6500 knows about are advertised out to each of the nine locations.
2. The 4006's are all advertising thier directly conencted routes to the 6500.
Onto the location I was testing at:
The 4006 where I was testing at has four vlan interfaces enabled and they are in an UP/UP state. The ip routes from the 4006's directly conencted vlan interfaces propogate to the 6500 at our core location and the 6500 sucsefully propgates these learned routes to all the other 4006's.
This past Friday I configured a 3750x with two /22 vlan interfces and one physical gi port with an IP address and also configured on Ethernet port on the 4006 with an IP address in the same network block as the 3750x gi interface (a /30 netowrk block). I saw both interfaces come up and EIGRP sucesfully established a neighbor adjecency between the 3750x and the 4006.
I noticed that the 3750 advertised out all of it's directly conencted routes to the 4006 and the 4006 advertised it's directly conencted routes to the 3750. However, the 4006 did not advertise any of the routes it had learned from the 3750x to the 6500 and nor did the 4006 advertise any of the routes it had learned from the 6500 to the 4006. My suspicion is that the "eigrp stub connected summary" statement is enabled on both the 4006 and 3750 thus prevenintg them form advertising out any routes other than thier directly conencted routes. Can any of you verify that I'm either correct or inccorect about this?
here are the eigrp statemnets from the 6500 and 4006:

In my ongoing project i need to monitor cisco 3750-X port status (uplink/downlink) i.e. whenever there is some problem at a specific port. I need to monitor it through an OPC server and right now what i am doing is as follows: i am using Kepserver and i have added SNMP driver in it for that purpose i am not a networking expert but what i have learnt till now is that SNMP agent (that resides in switch) delivers the status of MIBs to SNMP manager ( which in my case is kepserver (opc server)) for the above purpose i am adding IF-MIB to monitor OID 1.3.6.1.2.1.2.2.1.8 (which shows port statuses) but when i add that in OPC server then it indicated that this OID is not available in the Switch ( it might be disabled) so i need to ask if there is any way to enable OID's in a switch,
View 0 Replies View RelatedI would like to apply a policy-based route on one of our L3 switches (Cisco 3750) to change the next-hop of a couple of servers only. The VLAN where those servers reside got WCCP enabled on it. When I want to apply the route-policy to that VLAN interface it doesn't let me. When I try to apply the same policy to a VLAN interface without WCCP it does work. Is there any Cisco IOS limitations that would prevent me from doing that?

View 4 Replies View RelatedIf I have two stackable switches one switch uplinks to one 6509 core switch and the other connection uplinks to another 6509 core switch, and also the other stackable switch does not connect to the core switches. Because I am using hsrp and also we are not using vss then one uplink to the core is not in used only ones is so then how does creating an etherchannel between does two uplinks to both core switches benefit me in anyway such as more bandwith and using both uplinks at the same time or I'm I wrong?

I am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)
View 5 Replies View RelatedI have a simple design with 3750. I configured a route-map which define a next hop. I defined this route-map on a policy on a vlan interface.When I test some ping and a debug ip policy and it seems that my policy never match.Is there any mechanism that prevent the switch from using PBR? I think of CEF .

I have a small campus network using 3750 stackable switches and a 3725 router (see diagram below). Currently the 3725 router is handling inter-vlan routing for the campus and it looks like it's not able to handle the amount of traffic we're pushing. The router CPU sometimes hits above 90% due traffic load. What I would like to accomplish is move L3 process over to the 3750 MDF stack and the IDF1 stack. I am thinking creating SVI's on both MDF stack and IDF1 stack, run HSRP between the two stacks and may be do load balance traffic between the two stack as well.
View 8 Replies View RelatedLooking for feedback from other organizations that have large 3750 stacks. I've got one stack of (8) 3750's composed of (6) 3750G's and (2) plain 3750's. This particular stack is usually unresponsive to SNMP queries and often fails to write config when we make changes. After a couple tries it will finally go. Part of my probably here is likely the plain 3750's that always boot faster and come up as the master. I should manually set the master to one of the G's. What I'm wondering is who else has 7-9 3750's stacked and are they performing well for SNMP, telnet, etc? I've got another newer stack of 7 3750E's that I need to add one more switch to. Need to decide if I want extended downtime to break the stack up or just add the 3750X to make member 8 and hope it performs well. I have 50+ 3750 stacks working great on our campus.
View 1 Replies View RelatedWe currently have a site with a very simple topology that uses a 3750X switch stack for a collapsed core. Everyday, the users have a conference call and experience poor voice quality.Its not bad when users call from several conference phones, but when everyone calls in on individual phones, there is choppy and almost inaudible voice quality experienced. The voice traffic flow would be as follows: Phone <-> 3750 switch <-> Voice GW We have packet captures showing that RTP packet loss is occuring from the phone to the voice gateway, but none from the voice gateway to the phones. We also have drops in the output queues that match drops on the asics. I can reset the counters and they will be clear until the call, and then they increment significantly during the call. The voice gateway and phones are non-Cisco. The switch stack has 6 switches. We are trusting the DSCP settings on the phones. All the queue drops from the phones are usually in queues 0-3, but all drops on the voice gateway is in queue 0. Below are the QoS settings; they are mostly default and we have not changed any queuing, thresholds, or buffers. Should we specify larger buffers and threshold for a designated queue and send EF traffic to that queue?

I have a small network using a 24 port 3750 switch. I need to add five computers in another room and only have one Cat 6 cable running there and no room left on the 3750. I got a 3650 to put in the new room with the new computers. The problem is, whenever I plug the new switch into the 3750, it shuts down the port and gives me an err-disable. I can do a shut/no shut and re-enable the port. I searched the web and read about trunking and clusters. I'm not sure which, if either, is appropriate. I see various documentation that shows you can put one switch behind the other. But nothing tells me the configuration which will allow it.
