I have CiscoWorks LMS 2.6 with CiscoView 6.1.5 & with version 4.0 of the WS-C3560X-48T-L device package. For some reaseon I'm getting the following when I try to bring up a 3560' in CiscoView's ChassisView
Message
Can't find applicable device package for 10.20.2.11.
Cause
Device package for this device type is not installed or device support for this device type might not be available or you are attempting to open a component inside a device.
Action
Please install a device package for the device type or open the parent device to manage the component.

Cisco Catalyst 3750-E
In the two previous posts I covered how to create multiple VLANs, trunk those VLANs between multiple stackable Avaya Ethernet Routing Switches utilizing Multi-Link Trunking and how to create Layer 3 IP interfaces to be used for routing IP packets between those VLANs.
In this post I thought I would expand the network topology of my previous two posts to include a Cisco Catalyst WS-C3750X-12S-S . I’ll specifically cover how to trunk (bridge) multiple VLANs between a stackable Avaya Ethernet Routing Switch and the Cisco Catalyst 3750-E and how to configure multiple interfaces in a Link Aggregation Group (LAG) utilizing LACP similar to Avaya’s proprietary MLT feature.

You
might be looking at the output above and asking yourself what’s “Trunk
32″?
Let me provide some quick background. You can have a total of 32 MLT/LAG trunks
on a stackable Avaya Ethernet Routing Switch. When you create LACP trunks the
switch automatically creates a LAG in the MLT table dynamically from the bottom
up. While in the previous post I created “Trunk 1″ by trunking ports 47 and 48 together
(see above), in this post I’ve created an LACP trunk on ports 45 and 46 which will be reported it
the WS-C3750V2-48PS-S switch as “Trunk 32″. You can also see it in the MAC/FDB table above.

3750s stack or Catalyst 6500?
i'm working in a government health network and we actually have a Cisco Catalyst 4503 as a Core Switch with a bunch of 2960Gs and 2950, etc. My question is regarding the best solution to have for having the Core Switch to change.
Scenario
1: 4x Catalyst 3750 24 Ports and 1x WS-C3750V2-24PS-S 12 ports all 5 stacked
Scenario 2: 1x Catalyst 6500 48 ports and another one 24 ports SFPs
I think both scenarios would be approximatly the same cost or around it, but it's not a matter of money. I would like to know what would be the best solution for us for scalability, fault tolerance, network management, etc.
The only flaw that I see going for 6500 is that it doesn't give me redundancy in terms of chassis. If you are planning to go for two supervisors in the chassis, it will be a better option.
1)
You can add/remove modules from 6500 as & when you want without having to
pay for any other switch, I assume that the modules would be cheaper than buyig
a whole new switch.
2)
It gives you more backplane speed.
3)
Hardware forwarding.
4) Most of routing & other functions would be handled in hardware.
Overall,
6500 is much more advanced than 3750.
So,
I would go for 6500. For more details, I would suggest going through the
datasheet of both these WS-C3750X-24P-S switches.

cisco 3750 high cpu
We
have a cisco WS-C3750X-24T-L that sometimes shows high cpu.
Please
see details below. When cpu was running high, we noticed
2 process that seems to be the culprit. One is VMATM Callback and one is IP Input.
What
is VMATM? Can't seem to find much documentation with it.
Also, IP Input seems to be well documented but I'm wondering how it ties into VMATM if it does?

This 'VMATM' process mainly takes care of the

OSPF on 3750 with IP Base?
Just doing a quick sanity check on my decision before I purchase but have found some conflicting information that I do with help clarifying!
I'm
purchasing a WS-C3750X-24T-L and need to run OSPF, can I do this with IP Base? The
Cisco product page would appear to say Yes, I quote:
"Software
versions
LAN
Base: Enterprise Access Layer 2 Switching
IP
Base: Enterprise Access Layer 3 Switching, including OSPF (Open Shortest Path
First) for routed access
IP
Services: Advanced Layer 3 Switching (IPv4 and IPv6) "
But
from everything else I've read on these forums only static routing is available
in IP Base along with RIP, can anyone shed some light on this? By Routed Access
does it simply mean OSPF can be used but only as a Stub area (much like EIGRP
with IP Base?)
Newly
released IOS version 12.2(55)SE WS-C3750X-24T-S support OSPF v1 ONLY.

problem getting iOS 15.0.2 to run on 3750-x 48ps-s
Trying to get the 10Gbps service module to be recognised requires V15 according to cisco WS-C3750V2-24PS-S docs
Upgrading
from V12.2 55 (or .58) fails on some switches I have tried
Process
fails and I finish up at the switch: prompt
I
can recover....
The
switch can be regressed back to v12.2.55 or .58
But I can't get all of them up to v15
I
have tried 5 to date
Same
methods producing different results
2
worked
3 failed
All our problematic switches are 48 ports ones, we have some 24 port ones but they're newer and aren't affected. Our testing of the affected switches suggests it's related to their age/hardware revision:
VO1
– fail to load image, get stuck in continual reboot, eventually fail to ROMMON.
VO2
serial number beginning FDO15 – freeze whilst loading image.
VO2
serial number WS-C3750X-24P-S beginning FDO16 and up – work fine.

add swich to stack (cisco 3750)
I want to add 2 switches to my stack of 2.
Switch 1 is the top switch in rack and has a
priority of 15
Switch WS-C3750X-24P-S 2 the is second switch in rack and has
priority of 14
How can I configure the stack (provision
configuration) so that the 3rd switch in
rack will get switch number 3 and the 4th switch in rack gets number 4
All swiches are exact same module
Just
do one-by-one method with following configuration only from the stack master.
Switch(config)# switch 3 provision switch_PID -
put your 3rd switch into stack.
Verify the status of the provisioned switch.
For stack-member-number, enter the same number as in Step 1.
Switch(config)# switch 4 provision switch_PID -
put your 4th switch into stack.
Verify and save the config.
Note - switch_PID:
For type, enter the model number of a supported
switch that is listed in the command-line help strings.
change the stack member number by using the
switch <current-stack-member-number>
renumber <new-stack-member-number> global configuration command,
show swithc will show the current swithc number
and priority
3750-Stk>show switch

the new number goes into effect after that
stack member resets (or after you use the reload slot stack-member-number
privileged EXEC command) and only if that number is not already assigned to any
other members in the stack.
A higher priority value for a stack member
increases its likelihood to be elected stack master and to retain its stack
member number. The priority value can be 1 to 15. The default priority value is
1. You can display the stack member priority value with the show switch user
EXEC mode command.

Cisco recommends that you assign the highest
priority value to the switch that you prefer to be the stack master. This
ensures that the switch is re-elected as stack master if a re-election occurs.
How do you change the priority value?
From
the global configuration mode, issue the command switch stack-member-number
priority new-priority-value .
From
the bootloader switch: prompt, issue the command set SWITCH_PRIORITY
new-priority-value .
Even though the priority value applies
immediately to the member, it will not affect the status of the current stack
master. New priority value will play a role in the next stack-master election.
Yes the switches will retain their numbers even
if you set different priorities.
The priority sets which switch in the stack
becomes the master. The number is just
that - the number of the switch WS-C3750X-24P-L in the stack. Once it's set the number won't change unless
you change it in the config.
