Catalyst 6500 MSFC telnet access from FWSM

I am testing if it is possilble to telnet the Catalyst 6500 MSFC from the FWSM CLI command but cant seems to make it. Anyone has an idea how do do it? I want this to work for faster troubleshooting in case of failure of FWSM. Hoping for your help. Thanks

I don't think you can telnet from the FWSM shell to anywhere since FWSM doesn't include a telnet client, nor a ssh client.
You probably already know the reverse, getting to the FWSM cli from a MSFC-- (session slot x processor 1) where x is the slot the FWSM is installed at in the chassis.

How to remove the WiSM2 from the Catalyst 6500 series switch?

Hello, can you explain to me how to safely remove the WiSM2 from the Catalyst 6500 series switch?
According to the documentation "Catalyst 6500 Series Wireless Services Module 2 Installation and Verification Note":
To remove the WiSM2, perform these steps:
Step1     Shut down the module by one of these methods:
In privileged mode from the router prompt, enter the hw-mod module mod shutdown command. NoteIf you enter this command to shut down the module, you must enter the following commands in global configuration mode to restart (power down, and then power up) the module:
Router# no power enable module modRouter# power enable module mod
If the module does not respond to any commands, press the SHUTDOWN button located on the front panel of the module.
Step2     Verify that the WiSM2 shuts down. Do not remove the module from the switch until the POWER LEDis off.
But, in the case of Step1 (1st methods) I do not see a option "shutdown" in the command "hw-mod module 3"...
All I prompted to enter is:
c6500#hw-module module 3 ?
boot           Specify boot options for the module through Power Management Bus control register
reset          Reset specified component
simulate Simulate options for the module
Is it hidden options? IOS version of c6500 is 12.2(33)SXJ1
In the case of Step2 (2nd methods) there is not any button on the front panel of the module?
And yet, it is better to remove the module configuration manually or use the command module clear-config prior to removing the module?

Good catch.
Which one is true, will get back to you on this if i've something soon.

Connection of LC/APC fiber patch cords to Cisco Catalyst 6500 $ Cisco Access 3750 Switches

I have an LC/APC fiber patch cord infrastructure and I want to connect it to Cisco Catalyst 6500 & Cisco Access 3750 Switches. what type of transceiver should be used?
I read a note on Cisco website stating the following for Cisco SFP+ transceivers:
Note: "Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC connectors are not supported. All cables and cable assemblies used must be compliant with the standards specified in the standards section"

Thank you, but my question is that I have a single mode fiber patch cord with LC/APC connector while cisco stating a note that only use LC/PC or LC/UPC type of connectors with SFP+ transceiver.
So what type of transceiver should I use to connect LC/APC patch cord to cisco switches? Is there another type or SFP+ still can be used?

Denying Telnet Access on Catalyst 6509

Hello,
I was wondering if anyone could tell me how to disable or deny telnet access to my 6509s (CATOS). I recently put a crypto image on and I have SSH running. I would like to replace telnet access with SSH for remote management. However, I couldn't find a way to turn telnet off...right know both SSH and telnet are working, which kind of defeats the purpose of me putting the crypto image on.
I was able to do this on my IOS switches with the command: switch(config-line)#transport input ssh.
Thank you,
Scott

Just read your post correctly and deleted my last post...DOH!
You can use ip permit lists on CATOS
# set ip permit
ds-sw> (enable) set ip permit 1.1.1.1 ?
Set IP permit mask
telnet Set telnet permit entry
snmp Set snmp permit entry
I'm running an old version of CATOS on a 5500 which doesn't support SSH but you should see SSH on your list of protocols.
I think you will need use "clear ip permit telnet" first.

Configuring the Catalyst 6500 Switch for IPS Inline Operation of the IDSM

I understand how to configure the Catalyst 6500 switch so that the monitoring ports are access ports in two separate VLAN's for inline operation.
However, I don't see any documentation that describes how the desired VLAN traffic gets forced through the IPS.
In promiscuous mode, you can use VACL's to copy/capture and forward the desired traffic to the IDSM for analysis. I'm not seeing how to get the desired traffic through the IPS.
Note that the host 6500 is running native IOS 12.2(18)SXE.
Thanks for any assistance.

A tranparent firewall is a fairly good comparison.
Let's say you have vlan 10 with 100 PCs and 1 Router for the network.
If you want to apply a transparent firewall on that vlan you can not simply put one interface of the firewall on vlan 10. Nothing would go through the firewall.
Instead you have to create a new vlan, let's say 1010. Now you place one interface of the firewall on vlan 10 and the other on vlan 1010. Still nothing is going through the firewall. So now you move that Router from vlan 10 to vlan 1010. All you do is change the vlan, the IP Address and netmask of the router stay the same.
The transparent firewall bridges vlan 10 and vlan 1010. The PCs on vlan 10 ae still able to communicate to and through the router, but must go through the transparent firewall to do so.
The firewall is transparent because it does not IP Route between 2 vlans, instead the same IP subnet exists on both vlans and the firewall transparently beidges traffic between the 2 vlans.
The transparent firewall can do firewalling between the PCs on vlan 10 and the Router on vlan 1010. But is PC A on vlan 10 talks to PC B on vlan 10, then the transparent firewall does not see and can not block that traffic.
An InLine sensor is very similar to the transparent firewall and will bridge between the 2 vlans. And similarly an InLine sensor is able to InLine monitor traffic between PCs on vlan 10 and the Router on vlan 1010, but will not be able to monitor traffic between 2 PCs on vlan 10.
Now the router on one vlan and the PCs on the other vlan is a typical deployment for inline sensors, but your vlans do not Have to be divided that way. You could choose to place some servers in one vlan, and desktop PCs in the other vlan. You subdivide the vlans in what ever method makes sense for your deployment.
Now for monitoring multiple vlans the same principle still applies. You can't monitor traffic between machines on the same vlan. So for each of the vlans you want to monitor you will need to create a new vlan and split the machines between the 2 vlans.
In your case with Native IOS you are limited to only 1 pair of vlans for InLine monitoring, but your desired deployment would require 20 vlan pairs.
The 5.1 IPS software has now the capability to handle the 20 pairs, but the Native IOS software does not have the capability to send the 40 vlans (20 pairs) to the IDSM-2.
The Native IOS changes are in testing right now, but I have not heard a release date for those changes.
Now Cat OS has already made these changes. So here is a basic breakdown of what you could do in Cat OS and you can use in preparation for a Native IOS deployment when it gets released.
For vlans 10-20, and 300-310 that you want monitored you will need to break each of those vlans in to 2 vlans.
Let's say we make it simple and add 500 to each vlan in order to create the new vlan for each pair.
So you have the following pairs:
10/510, 11/511, 12/512, etc...
300/800, 301/801, 302/802, etc....
You set up the sensor port to trunk all 40 vlans:
set trunk 5/7 10-20,300-310,510-520,800-810
(Then clear all other vlans off that trunk to keep things clean)
In the IDSM-2 configuration create the 20 inline vlan pairs on interface GigabitEthernet0/7
Nw on each of the 20 original vlans move the default router for each vlan from the original vlan to the 500+ vlan.
At this point you should ordinarily be good to go. The IDSM-2 won't be monitoring traffic that stays within each of the original 20 vlans, but Would monitor traffic getting routed in and out of each of the 20 vlans.
Because of a switch bug you may have to have an additional PC moved to the same vlan as the router if the switch/MSFC is being used as the router and you are deploying with an IDSM-2.

Hi, I have a Catalyst 6500 with X6K-SUP2-2ge, the IOS and bootlader image been wiped out, it starts in ROMmon SP modw and I can't switch to RP to start download the IOS using Xmodem, though Xmodem shouldn't work in ROMmon SP mode but the it's not gving the
not executable message, the slot0: and disk0: are not accessable can't see the files inside, when I try the dir slot0: or dir disk0: it says it can't be opened and when I try to boot from them there's noting as well, what can I do to load an IOS image to the booflash: or slot0: ,each time I load the image using Xmodem at the end it gives me *** System received a Software forced crash ***

BTW System Bootstrap, version 7.1
I''m looking to format the PCMCIA using a PC and format it to FAT16 and copy the boot image into it and then try to load from the PCMCIA afterward if it works I'll format it using the Supervisor engine 2.
Any one have another new idea I can use, thanks in advance

This is a potentially complex issue.
Is this SUP configured to run as IOS native or CatOS Hybrid?
While in ROMMON can you do the 'dev' command and see whad drives are recognized. Then 'dir' the drives that the SUP recognizes.
Can you provide the screen captures as it boots?
You would be bette served by hacing a TAC case.

IDSM on catalyst 6500 to provide IOS Inline mode support

I am currently evaluating what kind of method to apply in my 6500. I would like to ask if IOS Version 12.2(33)SXI2a support inline mode and inline vlan pair mode with IDSM-2???what configuration should be done with the switch in order for the multiple vlan traffic to flow with an inline interface of the IDSM2??? In my case I have 16 user vlans and 1 server vlan on catalyst 6500...The task is to protect the servers from users....The requirement is to configure inline mode to monitor the traffic from these 16 vlans when they access the servers...But as we know the IDSM-2 has only two logical sensing ports...So my question is how will you configure the switch to forward the traffic from these 16 vlans to the IDSM-2 module via only ONE sensing port, since the other sensing port will be configured in the server vlan??? Because as far as i know, when you configure inline mode on IOS,you will have to configure the sensing ports in access mode( While in CatOS, you configure these as TRUNK ports)...But this will work when you have only two vlans...But in my case, I have 16 vlans to monitor in inline mode..Please suggest any solution.
Any urgent reply will be much grateful...
Many Thanks in advance

Hi Mubin,
If you're looking to monitor all the traffic from the user VLANs to the server VLANs then the simplest way to configure the IDSM-2 would be inline on the server VLAN segment. All traffic destined to the servers (from the users or anywhere else) has to traverse that VLAN. Assuming you have something like this to start:
VLAN 100-120 (users) ====== Switch ------ VLAN 200 (servers)
you'd drop the IDSM-2 inline on VLAN 200 by using a helper VLAN:
VLAN 100-120 (users) ====== Switch ----- VLAN 201 (server gateway) ----- IDSM-2 (bridging 201 to 200) ----- VLAN 200 (servers)
To do this you'll need to perform the following steps:
1. Designate a new VLAN to use as a helper VLAN for your current server VLAN. I'll use 201 for this example and assume your current server VLAN is 200.
Create the helper VLAN on the switch:
switch# conf t
switch(config)# vlan 201
2. Configure the IDSM-2 to bridge the helper VLAN and the server VLAN (200-201)
sensor# conf t
sensor(config)# service interface
sensor(config-int)# phsyical-interface GigabitEthernet0/7
sensor(config-int-phy)# admin-state enabled
sensor(config-int-phy)# subinterface-type inline-vlan-pair
sensor(config-int-phy-inl)# subinterface 1
sensor(config-int-phy-inl-sub)# vlan1 200
sensor(config-int-phy-inl-sub)# vlan2 201
sensor(config-int-phy-inl-sub)# description Server-Helper pair
sensor(config-int-phy-inl-sub)# exit
sensor(config-int-phy-inl)# exit
sensor(config-int-phy)# exit
sensor(config-int)# exit
Apply Changes:?[yes]:
3. Configure the switch to trunk the helper and server VLANs to the IDSM-2 module. I assume the module is in slot 5 in the example. Replace the 5 with the correct slot for your deployment:
switch# conf t
switch(config)# intrusion-detection module 5 data-port 1 trunk allowed-vlan 200,201
switch(config)# intrusion-detection module 5 data-port 1 autostate include
*Warning! This next step may cause an outage if everything is configured correctly. You'll probably want to schedule a window to do this.*
4. Finally, force the traffic from the server VLAN through the IDSM-2 by moving the server VLAN gateway from VLAN 200 (where it is currently) to the helper VLAN you created. To do this, remove the SVI from VLAN 200 and apply the same IP address to VLAN 201. I assume the current server gateway is 192.168.1.1/24
switch# conf t
switch(config)#int vlan 200
switch(config-int)#no ip addr
switch(config-int)#int vlan 201
switch(config-int)#ip addr 192.168.1.1 255.255.255.0
switch(config-int)#exit
switch(config)#exit
switch# wr mem
Now, when the servers try to contact 192.168.1.1 (their gateway) they'll have to be bridged through the IDSM-2 to reach VLAN 201 and in the process all traffic destined to them or sourced from them will be inspected. Do not put any hosts or servers in the helper VLAN (201) or they will not be inspected.
Best Regards,
Justin

Migrating from FWSM to ASA Service Module (ASASM)

I'm migrating from a failover pair of FWSM modules across to a failover pair of ASA Service Modules. In order to avoid a "big bang" switchover I intend to migrate subnets from one to the other over a protracted period.
With that in mind, can anyone confirm whether there is any restriction on having FWSM and ASASM modules in the same chassis? A trawl of the relevant documentation hasn't revealed anything.
In this specific case it is Catalyst 6509E VSS chassis pairs with Sup-2T.
Thanks in advance.

So long as the chassis has enough power to power these modules you are good.
Upto 4 FWSMs can be installed in a chassis.
Upto 4 ASA-SM modules can be installed in a chassis.
FWSM:
http://www.cisco.com/en/US/prod/collateral/modules/ps2706/ps4452/product_data_sheet0900aecd803e69c3.html
• Up to 4 FWSMs (20 Gbps) per Catalyst 6500 chassis
ASA-SM
http://www.cisco.com/en/US/prod/collateral/modules/ps2706/ps11621/qa_c67-662207.html
Q. How many ASA Services Modules can I place in a Cisco Catalyst 6500 Series chassis?
A. Up to four independent ASA Services Modules can simultaneously run in a Cisco Catalyst 6500-E Series chassis.

Firewalling vlans on Catalyst 6500 by using Cisco ASA Firewalls

Hello,
How to secure vlans on Catalyst 6500 by using Cisco ASA Firewalls?
There are no free modules on Catalyst 6500 to install a FWSM module.
What is the best configuration to secure vlans (~80 vlans) by using cisco ASA firewalls (context, hairpining...)?
Thanks

Hi Bro
Just to understand your question once again, you don't have anymore available slots in your present Cat6K, but you want to know how to secure your VLANs or SVIs that has been configured in your Cat6K?
If you were to ask me, I would not apply a bunch of ACLs in the Cat6K, for starters. You might wanna look into COPP (Control Plane Policing) instead. Furthermore you could also refer to this Cisco document http://www.cisco.com/en/US/products/hw/switches/ps708/products_white_paper09186a00801b49a4.shtml
However, if you do have Cisco ASA FW appliance (not module, I presume from your question), you could enable ACLs, threat-detection feature, IP Audit features, reverse-path policing, capping of the embryonic values etc.
P/S: If you think this comment is useful, please do rate them nicely :-)

Securing Telnet access on Cisco routers (access class)

Dear All,
In all my network i have cisco catalyst switch and cisco routers deployed in my WAN. In cisco routers, it was activated an ACL to secure telnet access to WAN devices. only 3 hosts (remote) were autorized to access these devises. I need to modify this secuirty to have access from the LAN (locally).
The ACL was implmented in all routers, and activated using access class in.
in there any idea without changing more the configuration and only tell the router to apply this ACL for WAN and not access for the LAN ?
Thanks for your help,
Best regards,

Catalyst 6500 - Nexus 7000 migration

Hello,
I'm planning a platform migration from Catalyst 6500 til Nexus 7000. The old network consists of two pairs of 6500's as serverdistribution, configured with HSRPv1 as FHRP, rapid-pvst and ospf as IGP. Futhermore, the Cat6500 utilize mpls/l3vpn with BGP for 2/3 of the vlans. Otherwise, the topology is quite standard, with a number of 6500 and CBS3020/3120 as serveraccess.
In preparing for the migration, VTP will be discontinued and vlans have been manually "copied" from the 6500 to the N7K's. Bridge assurance is enabled downstream toward the new N55K access-switches, but toward the 6500, the upcoming etherchannels will run in "normal" mode, trying to avoid any problems with BA this way. For now, only L2 will be utilized on the N7K, as we're avaiting the 5.2 release, which includes mpls/l3vpn. But all servers/blade switches will be migrated prior to that.
The questions arise, when migrating Layer3 functionality, incl. hsrp. As per my understanding, hsrp in nxos has been modified slightly to better align with the vPC feature and to avoid sub-optimal forwarding across the vPC peerlink. But that aside, is there anything that would complicate a "sliding" FHRP migration? I'm thinking of configuring SVI's on the N7K's, configuring them with unused ip's and assign the same virtual ip, only decrementing the prio to a value below the current standby-router. Also spanning-tree prio will, if necessary, be modified to better align with hsrp.
From a routing perspective, I'm thinking of configuring ospf/bgp etc. similar to that of the 6500's, only tweaking the metrics (cost, localpref etc) to constrain forwarding on the 6500's and subsequently migrate both routing and FHRP at the same time. Maybe not in a big bang style, but stepwise. Is there anything in particular one should be aware of when doing this? At present, for me this seems like a valid approach, but maybe someone has experience with this (good/bad), so I'm hoping someone has some insight they would like to share.
Topology drawing is attached.
Thanks
/Ulrich

In a normal scenario, yes. But not in vPC. HSRP is a bit different in the vPC environment. Even though the SVI is not the HSRP primary, it will still forward traffic. Please see the below white paper.
http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9402/white_paper_c11-516396.html
I will suggest you to set up the SVIs on the N7K but leave them in the down state. Until you are ready to use the N7K as the gateway for the SVIs, shut down the SVIs on the C6K one at a time and turn up the N7K SVIs. When I said "you are ready", it means the spanning-tree root is at the N7K along with all the L3 northbound links (toward the core).
I had a customer who did the same thing that you are trying to do - to avoid down time. However, out of the 50+ SVIs, we've had 1 SVI that HSRP would not establish between C6K and N7K, we ended up moving everything to the N7K on a fly during of the migration. Yes, they were down for about 30 sec - 1 min for each SVI but it is less painful and waste less time because we don't need to figure out what is wrong or any NXOS bugs.

Restrict telnet access for specific users on ios router

aaa new-model
aaa authentication login default local
username aaa password aaa
username bbb password bbb
user aaa should have ssh and telnet access.
user bbb is only used for vpn authentication, i dont want him to access router via ssh or telnet ,even in user exec mode.
i also can not apply access-class on vty lines because i am loging in device from different places ,and dont know exact ranges of ip address to create access-list
radius and tacacs is not option for me
what can be done in order to restrict user bbb from ssh and telnet access ?

OK. I did not clearly remember the OP description of aaa and bbb. So for bbb to only have VPN access try
User bbb password bbb privilege 0

Modules Gbic Catalyst 6500

I have a peculiar problem with two gbic modules of Catalyst 6500.
First problem, I have a gbic port in module 7, which was a trunkport to Catalyst 2950, that does not allow conection to switch Catalyst 2950, and besides it harmed the yield of Catalyst 6500. I have to disconnect the optical fiber cable so that everything returned to normality.
Second problem. A port gbic in module 8, I let work and I disconnect of the network to one of the servants, by such reason I had to connect the fiber cable in another one gbic of he himself I module.
My question is: is necessary to change I modulate 7 and 8 not to have network problems on watch? or single to change gbic affected in each one of the modules?
Thank you,

Failure to get GBIC up during installation could be as a result of system requirements not met, incorrect cable installed, lack of power to the device, configuration errors or hardware failure. Verify that the GBIC cable is connected to another active network device and that the port is not shut down. Replace cable with a known good cable. Make sure GBICs are matched on either side of the connection. Make sure the flow control and port negotiation settings are consistent on both sides of the link. There may be incompatibilities in the implementation of these features if the switches being connected are from different vendors. If in doubt, turn these features off on both switches. Swap GBIC to a different slot. Also, try using a spare GBIC to see if it works. For more information, refer to Troubleshooting link :

Context Migration from FWSM to ASA

Hi there ,
     What would be best way to migrate a Context from FWSM to ASA (non SM) with minimal down time & effort .
I am thinking of these steps :
1) Preconfigure the new ASA with the same IP-Address as FWSM for the interfaces (keep the ASA subinterfaces in shut state ) , configure Access rules .
     ( Want to retain same ip for the interfaces , since there are many hosts behind the FWSM with this gateway IP configured )
2) Shut the context specific interfaces on FWSM & bring up the Context specific interfaces on the ASA.
   ( Also a query - If I introduce ASA into the Network with the same IP as of FWSM , though the interfaces would be in shut state , should i expect any IP Conflicts )
Thanks

Hi,
Well you probably have the option to configure the old FWSMs interface MAC address to the ASAs corresponding interface manually, this way there will be no change in the ARP from the perspective of the server/host.
I guess depending on if you have a single firewall or failover firewall the command is a bit different as you define either 1 or 2 MAC addresses.
I think this was the command to modify the MAC address
