Using Ciscoworks to update netmask on mgmt interface for multiple switches

Is it possible to user Ciscoworks LMS 3.2 to update the netmask for a management interface on multiple switches? For example, say I have a 3750 access switch management network, 172.28.185.0/27 (default gateway 172.28.185.1) that we're resizing to a /26. Is there a simple way to update just the netmask for the management interface on those devices using Netconfig?
-David

Unfortunately not. You could use Netconfig or even baseline compliance for this, but since you need to know each interface's IP, that means you'd have to create parameterized templates. Therefore, you would have to create a template "answer" file for each device in this subnet which had their IP address for the interface in question.
Baseline compliance might be a little easier with a template like:
Commandlet : CheckIP
IsPrereq : Yes
Submode : interface [#.*Ethernet.*#]
+ ip address [#172.58.185.\d+#] 255.255.255.224
Commandlet : ReplaceIP
Parent : CheckIP
+ ip address [IP] 255.255.255.192
You would still need to provide a value for [IP] for each device when performing a deployment.

Loopback interface on catalyset switches

Hello,
for admin, I need to create loopback interface and use it as the admin IP to reach the switch
I know that the admin ip configured under interface vlan1
but I'm asking because I have a switch that has the int loopback in his menu when using

Configure interface vlan on switch 3524 XL

Hi all,
I have an old switch C3524 running image "C3500XL-c3h2s-mz-120.5.2-xu". I had successfully created vlan 120 but when I config "interface vlan 120" as follows:
swicth # conf t
switch(config-subif)#interface vlan 120
switch(config-subif)#ip address 172.10.10.1 255.255.255.0
switch(config-subif)#no shut
then show run does not see this interface. Show vlan indicates vlan 120 is active.
Please help. thank you.

you're right. I just shut down interface vlan 10 (interface vlan 1 is down already) then interface vlan 120 comes up. Question is: if I need to configure several ports: some in vlan 10 and some in vlan 120 then should I have interface vlan 10 up too ?
Thank you very much.

Problem with FWSM and L3 interface in same switch

I have two 6513s with an 802.1q trunk connecting them. Each switch has redundant Sup720s running in Native mode, IOS ver 12.2(18)SXF (they were initially running SXD3). A FWSM (ver 2.3(3), routed mode, single context) is in each switch, setup in failover mode.
I can not get a PC, in a vlan that has the layer 3 interface defined on the switch with the active FWSM in it, to communicate with devices "behind" the FWSM. If I move the layer 3 configuration for that vlan to the other 6513, everything works fine.
The MSFCs are on the inside of the firewall, they have a layer 3 interface configured in the same vlan as the FWSM "inside" interface. Several "same security level" interfaces are defined on the FWSM and used to protect server farms. I am using OSPF on the MSFCs and FWSM and the routing table is correct.
The FWSM builds connections for attempts made by the PC with the layer 3 interface defined on the same switch as the active FWSM just fine, so this is not a FWSM ACL problem.
A ping of the FWSM "inside" interface from a PC with the layer 3 interface defined on the same switch as the active FWSM fails, even though debug icmp trace on the FWSM shows the request and the response. A packet capture, using the NAM-2, shows only the request packets. I have captured on the common vlan and the FWSM backplane port channel interface.
Just to add to the confusion, if I capture in the same places, but do the ping from a PC that is in a vlan with the layer 3 interface defined in the 6513 that does not contain the active FWSM, which works fine, I see the request and reply on the common vlan capture, but only the request on the port channel capture.
This problem has been there from the beginning of this implementation and has not changed with IOS and FWSM software upgrades. I have experienced this with any and all vlans that I tried to define the layer 3 interface for on the switch with the active FWSM. I have MLS turned on.
If anyone else has experienced this and solved it, or knows what is going on, I would appreciate any insight.
Thanks.
Keith

I will have to get setup to record more data, but I do know the FWSM showed a ping request and a ping reply at the "inside" interface.
I believe my problem is related to the IOS command "firewall multiple-vlan-interfaces" which I put in place to allow IPX traffic to be brought around the FWSM. The little documentation that there is for this command, states that policy routing may need to be implemented to prevent ip packets from going around the firewall. I do not have any policy routing in place.
I also do not have any active layer three interfaces defined for any of the vlans assigned to the firewall except the "inside" interface. So my resoning was that I did not need to be concerned about ip packets having a way around the FWSM. My suspicion is that this command and the fact that I have mls on is causing some type of a problem which results in the packet being "lost" when it needs to be going through the MSFC in the switch with the active FWSM to get to the PC. Hopefully that makes some sense.
Do you have any idea where better documention on using the "firewall multiple-vlan-interfaces" may be, or a better explanation of all that is happening inside the switch when that command is used?
Thanks.

Wism interfaces gone after switch-upgrade

Hi,
I've a 6509 with a sup720 (ordinary, not a 10GE) and a wism blade in slot 3.
It worked fine until i did a upgrade of the IOS on the 6509. I went from s72033-ipservicesk9_wan-mz.122-18.SXF13 to s72033-advipservicesk9_wan-mz.122-33.SXI3.
Now i cannot reach my Wism-blade any more. When i look in the running config on the switch there are no gigabit-interfaces on module 3, in the config there is even no mention of a module 3.
However when i do a "show module" the wism is reported with a status "ok". Also when i do a "show wism module 3 controller 1 status" it tells me that its "Oper-up" and all the adresses are in place, even the service IP-adres (which i do not understand because it can only get this adres by DHCP from the switch).
The Wism is running 6.0.188.0.
Anyone ever seen such behavior?
Thx

Elie, the service-vlan was (and is) indeed different, so that was not the problem. I got a good clue in the posting of dampcampb: he wrote that there was a difference in behavior between the SXI- and the SXF-versions of the IOS. I checked and there was also a SXF-version with the features i wanted. I used that version of the IOS and all was working fine again. Thx however for the reply.

Global vs interface command on switch

Hello,
If I have a command globally which applies on all switch ports but then I want to configure one port with a different command not apply the global command on the switch. When i configure that port will it take effect the new command configure for that port and disregard the global command that was apply on all ports or the global command still take effect and interface command not take effect?

Some of the most common commands that are used on a per-interface level (which overrides the global commands) are:
1. STP;
2. UDLD;
3. PoE control;
4. Auto Switch Port macro (ASP)

ASA Redundant interfaces with stack switches

Hi All,
we have two ASA 5510 connected in failover, and a pair of cisco 2960s switch connected in stack.
Currently one interface of primary ASA is terminated on switch1 and a interface from standby is connected to switch2 as Inside, and switch1 and switch2 are in stack.
for redundancy purpose i want to use multiple interfaces of ASA for inside , so first i thought to use etherchannel , but it has a limitation that , it cannot be terminated on stack switch(as per cisco document http://www.cisco.com/en/US/docs/security/asa/asa91/configuration/general/interface_start.html ).
So my question is :
1. can we use redundant interface feature where 2 physical interfaces combined to a redundant interface (eg interface redundant 1) for inside redundancy purpose.
2. Can these ports from primary/standby ASA terminated on stack switches (2960s), will this work (if the switch with active port goes down, will the other port take over in the redundant interface with the other switch).
I have attached the nw diagram,
Regards,
Ashraf

Hello Ashraf,
1. can we use redundant interface feature where 2 physical interfaces combined to a redundant interface (eg interface redundant 1) for inside redundancy purpose.
Sure, you can. That's the whole purpose of the feature.
2. Can these ports from primary/standby ASA terminated on stack switches (2960s), will this work (if the switch with active port goes down, will the other port take over in the redundant interface with the other switch).
It would make sense if that happens, as the status of the interface will be on a different state than up/up so failover to the other interface will be triggered,

Firefox interface lags badly (switching tabs, opening menus) , even in safe mode.

Switching between tabs, playing GIFs, playing YouTube videos, typing text and opening the Firefox menu are sometimes laggy.
For example, sometimes when I click on a tab to view it, there will be a delay of a second before its contents are shown.
I tried Google Chrome and it doesn't have this lag. My computer is pretty powerful.
I tried safe mode, but the problem was present there, too.
I tried clearing the cache, but no luck.
I'm not sure what else to say, so if you would like more information, please just ask! Thank you.

Hi amacfie,
Have you looked at our [https://support.mozilla.org/en-US/kb/firefox-slow-or-takes-too-long-start performance troubleshooting section]? There is a lot of good information in there that should help.
Hopefully this helps!

Which server is connected to a switch interface

Hi all,
We have a few switches in our company and we wanted to know an easy and quick way to find out which servers are connected to that switch (even if possible on which interface).
For example:
Firewall -> Switch1 interface Gig 0/1
Mail or 10.10.10.10 -> Switch2 interface Gig 0/3
I'm using at this moment the following command:
show cdp neighbors
It gives me all cisco device connected to that switch.
Is there an other command that does the same? Displaying the DNS or IP of a server that is connected to that interface of the switch.
Kind Regards

Hi,
a) there are some free tools available to track the end devices.
SolarWinds User Device Tracker might be an example (not tested personally).
b) If you want to run a CLI command, you usually need to take an opposite way: find out the device IP or MAC address and track to which switch port it's connected.
So you can list the FW ARP cache in your case.
And then to use "trace mac ip ..." switch CLI command, e.g.
See
http://www.cisco.com/en/US/customer/docs/switches/lan/catalyst3750/software/release/12.2_25_sec/command/reference/cli3.html#wp1917847

Hi,
A Tunnel interface is nothing more than just a process of putting another layer of headers onto an existing datagram to protect or hide its internal headers. There is no physical interface related to the operation of a Tunnel interface. Once a tunneled packet is created, it is forwarded through some other physical interface on the device that performs the tunneling.
There are two possible bottlenecks that ultimately define the bandwidth as seen by a Tunnel interface. The first bottleneck is the CPU of the router if the tunneling operations are performed in the operating system and not in specialized hardware. Too many packets to be tunneled can easily overwhelm the CPU and its capabilities. The second bottleneck is the physical inteface itself that will be used to send out the tunneled packet.
On Catalyst 3xxx switches, there is no hardware support for tunneling operations, meaning the GRE tunneling encapsulation and decapsulation is performed in software and must be executed on the CPU. While there is no official benchmark as far as I know, I estimate that with the CPU in a Cat3750G, the throughput of a GRE tunnel is, at most, in orders of Mbps or tens of Mbps in ideal conditions. I do not think anyone will be willing to guarantee this figure, as these devices are not really intended to terminate GRE tunnels.
Apart from that, however, you do not really care about the bandwidth command setting on Tunnel interfaces, as that command has no influence on the real throughput of this interface - it just influences routing protocols like OSPF and EIGRP in their best path selection, and it may impact QoS mechanisms if applied to the Tunnel interface. However, if none of this is of a concern, simply configure the bandwidth command on a Tunnel interface to, say, 1000 (meaning 1Mbps) and you should be fine.
Best regards,
Peter

How Could I assign Trunk on 6505 Switch Interface

Hi,
I am Facing a problem about assigning specific interface on 6505 switch as a trunk port that could pass specific tagged vlans, I would like to know how could I configure this interface as layer 2 interface and assign trunk that allows specic tagged vlans.
thanks

Hi,
Creation of vlan is common for all catalyst 6500 series.
For Creation,
set trunk mod_num/port_num [on | desirable | auto | nonegotiate] negotiate
For assinging specific vlans
set trunk mod_num/port_num vlans

Interface on asa.

Hi ,
I have connected a firewall inside interface to l3 switch.
on l3 switch
int gi0/1
no switchport
ip address 192.168.10.1 255.255.255.0
no shut
on firewall
int gi0/1
nameif inside
security level 100
ip address 192.168.10.2 255.255.255.0
If i ping to 192.168.10.2 from firewall thus it ping.
As i know inside host can ping to inside interface.But not any opposite interface such as dmz etc.(need access-list)

Hi Prashant,
Here are two things involved.
1. Ping to the far end interface.
The ASA will not allow to ping the far end interface, for example is you are a host connected on the Inside network and ping the Inside interface the ASA will reply, but if you try to ping the DMZ interface from a host on the inside this will not answer and is expected.
2. Permit traffic from lower to higer interfaces.
All the traffic from higher interface level to lower interface level is permitted by default but is deny the other way around, from lower to higher.
If you need to permit traffic from lower to higher you need to enter a access-list on the lower level interface to permit traffic to the higher security level (If you are on version 8.2 or earlier you might need to add a NAT rule)
For example:
Inside security level 100
Outside security level 0
Inside host 192.168.1.1
access-list outside_access_in permit ip any host 192.168.1.1
access-group outside_access_in in interface outside

PL/SQL and Java Swing interface

Everybody in this forum knows that Oracle is the best database around
with many functionalities, stability, performance, etc. We also know
that PL/SQL is a great language to manipulate information directly
in the database with many built in functions, OOP capability,
transaction control, among other features. Today an application that
manipulates information, which needs user interface, requires components
to be developed using different technologies and normally running in
different servers or machines. For example, the interface is done using
a dynamic HTML generator like JSP, PHP, PL/SQL Web Toolkit, etc.
This page is executed in an application server like Oracle iAS or
Tomcat, just to name two, which in turn access a database like Oracle to
build the HTML. Also rich clients like Java applets require an intermediate
server to access the database (through servlets for example) although
it is possible to access the database directly but with security issues.
Another problem with this is that complexity increases a lot, many
technologies, skills and places to maintain code which leads to a greater
failure probability. Also, an application is constantly evolving, new
calculations are added, new tables, changed columns. If you have an
application with product code for example and you need to increase its
size, you need to change it in the database, search for all occurrences
of it in the middle-tier code and perhaps adjust interfaces. Normally
there is no direct dependency among the tier components. On another
issue, many application interfaces today are based on HTML which doesn't
have interactive capabilities like rich-client interfaces. Although it
is possible to simulate many GUI widgets with JavaScript and DHTML, it is
far from the interactive level we can accomplish in rich clients like
Java Swing, Flash MX, Win32, etc. HTML is also a "tag-based" language
originally created to publish documents so even small pages require
many bytes to be transmitted, far beyond of what we see on the screen.
Even in fast networks you have a delay time to wait the page to be
loaded. Another issue, the database is in general the central location
for all kinds of data. Most applications relies on it for security,
transaction and availability. My proposal is to use Oracle as the
central location for interface, processing and data. With this approach
we can create not only the data manipulation procedures in the database,
but procedures that also control and manage user interfaces. Having
a Oracle database as the central location for all components has many
advantages:
- Unique point of maintenance, backup and restore
- Integrated database security
- One language for everything, PL/SQL or Java (even both if desired)
- Inherited database cache, transaction and processing optimizations
- Direct access to the database dictionary
- Application runs on Oracle which has support for many platforms.
- Transparent use of parallel processing, clusters and future
background technologies
Regarding the interface, I already created a Java applet renderer
which receives instructions from the database on how to create GUI
objects and how to respond to events. The applet is only 8kb and can
render any Swing or AWT object/event. The communication is done
through HTTP or HTTPS using Oracles's MOD_PLSQL included in the Apache
HTTP server which comes with the database or application server (iAS).
I am also creating a database framework and APIs in PL/SQL to
create and manipulate the client interface. The applet startup is
very fast because it is very small, you don't need to download large
classes with the client interface. Execution is done "on-demand"
according to instructions received from the database. The instructions
are very optimized in terms of network bandwidth and based on preliminary
tests it can be up to 1/10 of a similar HTML screen. Less network usage
means faster response and means that even low speed connections will
have a good performance (a future development can be to use this in
wireless devices like PDAs e even cell phones, just an idea for now).
The applet can also be executed standalone by using Java Web Start.
With this approach no business code, except the interface, is executed
on the client. This means that alterations in the application are
dynamically reflected in the client, no need to "re-download" the
application. Events are transmitted when required only so network
usage is minimized. It is also possible to establish triggering
events to further reduce network usage. Since the protocol used is
HTTP (which is stateless), the database framework I am creating will
be responsible to maintain the state of connections, variables, locks
and session information, so the developer don't need to worry about it.
The framework will have many layers, from communication up to
application so there will be pre-built functions to handle queries,
pagination, lock, mail, log, etc. The final objective is to have a
rich client application integrated into the database with minimum
programming and maintenance requirements, not forgetting customization
capabilities. Below is a very small example of what can de done. A
desktop with two windows, each window with two fields, a button with an
image to switch the values, and events to convert the typed text when
leaving the field or double-clicking it. The "leave" event also has an
optimization to only be triggered when the text changes. I am still
developing the framework and adjusting the renderer but I think that all
technical barriers were transposed by now. The framework is still in
the early stages, my guess is that only 5% is done so far. As a future
development even an IDE can be created so we have a graphical environment
do develop applications. I am willing to share this with the PL/SQL
community and listen to ideas and comments.

Is it sound like Oracle Portal?
But you want to save a layer 9iAS.
Basically, that was the WebDB.(Oracle changed the name to Portal when version 3.0)
Over all, I agree with you.
>>Having a Oracle database as the central location for all components has many

>>- Unique point of maintenance, backup and restore
>>- Integrated database security
>>- One language for everything, PL/SQL or Java (even both if desired)
>>- Inherited database cache, transaction and processing optimizations
>>- Direct access to the database dictionary
>>- Application runs on Oracle which has support for many platforms.
>>- Transparent use of parallel processing, clusters and future

I would like to build 'ZOPE' inside Oracle DB as a back-end
Using Flash MX as front-end.

Can I use DHCP snooping and IOS DHCP server on the same switch stack

Hello,
I am shortly going to be deploying a Cisco CallManager solution for a customer whose network comprises stacks of Catalyst 3850 switches.
There is no separate core/server farm switch so the CallManager servers, voice gateways and IP phones will all plug into the same stack and be in the same VLAN (not my choice!).
For security we want to enable DHCP snooping and were planning on using the IOS DHCP server on the Catalyst switch stack.
Will this work? - when I enable DHCP snooping in networks with separate access layer switches I set the uplinks to the core as trusted links.
I am not sure whether DHCP snooping will work in this case. Do I need to set the VLAN interface on the switch as trusted, is this even possible?
Unfortunately I do not have access to a layer 3 switch to test this at the moment.
Thanks

Nope. That's the issue.
They'll sync on a third device acting as a hotspot, but the device sending a signal is not "on" the network it creates so the airport is all by itself on that network. At least that is what it looks like to me. Anyone have another take on it? Seems pretty silly that an iPad can put out a wifi signal, an Airport Express can receive a wifi signal, and yet there is no simple way to get them to communicate under this particular condition.
