Is the 2960 Catalyst switch stackable?

I'm being asked to provide a comparison between switches and a specifically was asked if the 2960 switch is stackable. It's definitely rackable, but is it stackable?

Stackable switches are:
Layer 2 - 2975
Layer 3 - 3750

Recovery missing or corrupted IOS of Cisco 2960 Catalyst Switch

Dear Team,
I have Cisco 2960 48P switch, It is keep getting restarted and config was erased.
when I tried to run the IOS from hypertrm in room mode, I am getting below error..
My doubt is, is there any issue with hardware & what is the cause of for below error
suggest me, is there any option to upgrade the IOS?

Standard Catalyst switch vs. Enhanced routing version

I have question regarding the Cisco catalyst switches with the enhanced routing option.
As I understand it to do layer 3 routing between vlans on a standard catalyst switch IOS requires me to configure a port on the switch with 802.1Q, plug that port into a seprate router and configure the router's port (also configured with 802.1Q) as a 'router on a stick' for each vlan i need to route. Then any additional switches I want to add to the network I would simply trunk them back to the switch that has the router plugged in so i could have inter-vlan routing. Does this sound correct?
Now if I used a switch with the enhanced layer-3 IOS (A WS-C3560G-24TS-E for example) would i be able to remove the extra router from the design? would the packet routing go at the speed of the back-pane of the enhanced switch, rather than the wire-speed of the connection to a external router? I would also be able to get a gigabit SFP for each of my additional switches (3500XL's) and plug them into a trunked port on the 3560 thus giving a full gigabit trunk to each access layer switch.
Or would a router on a stick be a fine solution for inter-vlan routing? There will be a need for a integrated services router in the future to act as our CME for this site, so we will be purchasing a router anyways.

Hi Friend,
If you have layer 3 switch with standard image then also you will be able to configure intervlan routing on layer 3 switch.
Enhance image on layer 3 switch will let you configure routing protocols like ospf, bgp and enhance qos features whih is not possible with standard images.
But just for intervlan routing any layer 3 switch like 3550,3560 will let you achieve inter vlan routing without using external router.
Have a look at this link for intervlan routing on layer 3 switch like 350/3560 switches

The difference between VTP server and transparent mode on Catalyst Switch.

Hello
I have a question about the difference between VTP server mode and VTP transparent mode on general catalyst switch.
Basically VTP server mode can create and modify VLAN configuration but actually there is not any VLAN configuration through running-config, is it true? When I checked it on Cat3550, certainly there is not VLAN configuration on VTP server mode. But VTP transparent can create VLAN and configuration but does not synchronize with other switch VLAN status. I appreciate any related information and reason of the VTP server mode specification, thank you very much.
[VTP Transparent mode]
3550#sh vtp status
VTP Version : 2
Configuration Revision : 0
Maximum VLANs supported locally : 1005
Number of existing VLANs : 27
VTP Operating Mode : Transparent
VTP Domain Name :
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
*omit
3550#
3550#sh run

*omit
vlan 99

[VTP Server mode]
3550#sh vtp status
VTP Version : 2
Configuration Revision : 0
Maximum VLANs supported locally : 1005
Number of existing VLANs : 27
VTP Operating Mode : Server
VTP Domain Name :

Hi mhiyoshi,
3550#sh vtp status
VTP Version : 2
Configuration Revision : 0
Maximum VLANs supported locally : 1005
Number of existing VLANs : 27
VTP Operating Mode : Transparent

VTP Traps Generation : Disabled
*omit
3550#
3550#sh run

The above out put indicates that Vlan is created and then mode changed to transparent. i.e why revision no is 0.
3550#sh vtp status
VTP Version : 2
Configuration Revision : 0
Maximum VLANs supported locally : 1005
Number of existing VLANs : 27
VTP Operating Mode : Server
VTP Domain Name :
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
*omit
3550#
3550#sh run
Building configuration...
*no VLAN like above configuration on VTP transparent mode.
This indicates that vlan never created in server mode nor learnt from another switch as revision no is 0

The difference of the IEEE802.1x Auth between Cisco Routers and Catalyst switches

Hello
I am investigating the difference of the IEEE802.1x Auth between Routers and Switches.
Basically dot1x auth is availlable on Catalyst Switches. however if I want to check to
PortBased Multi-Auth , MAC address Auth and any certification Auth with this feature,
Is it possible to integrate into Cisco Router such as Cisco 891F ?
In my opinion Cisco891F is also available to use basic IEEE802.1x but if it compares with Catalyst switches such as Cat3560X
I think there might be any unsupported feature on Cisco 891F.
I appreciate any information. thank you very much in advance.

Many time in interviews asked comaprison between cisco routers and switches that i was answerless bcoz i dont have much knowledge about that.Can anyone provide me the compariosin sheet of the same.how are the cisco devices differ with each other how much Bandwidth each routres support and Etc...
Ummmm ... The most common question I get is "what is the difference between a router and a switch".
However, if you get a question like this, then my impression to this line of questioning are:
1. The candidate they are looking for has in-depth knowledge of routers and switches. And I mean IN-DEPTH!;
2. They are not looking for a candidate. They just want to stroke their ego. There is not alot of people who can give you the "names and numbers" of routers and switches at a snap of a finger. And if you do happen to know the answer, then and there, then expect a tougher follow-up question.

I don't understand correlation between ACL and dACL. If dACL is downloaded to the Catalyst switch what is the status of the ACL

Understanding ISE and dACL.
I don't understand correlation between ACL and dACL.
If dACL is downloaded to the Catalyst switch what is the status of the ACL attached to physical port. Is dACL appended to the existing ACL? When I typed ‘sh ip access-list int fa0/1’ I can see only dACL for access domain and dACL for voice domain appended to the previous dACL and no ACL lines.
Regards,
Vice

Hi,
Downloadable ACLs (dACL) are applied from your RADIUS server based on authentication and authorization policies. It overrides any standard interface ACL.
Standard interface ACLs are in place to limit traffic on the port before 802.1x or MAB authentication.
When an authenticated session terminates on the interface the standard ACL will be re-applied until the next authentication.

Can MPLS aware Netflow ver. 9 be enabled on the catalyst switches 6500

HI, I'm working for KOREA TELECOM, and currently providing MPLS VPN.
We're planning to provide our customer with traffic report using NetFlow..
I read some documents which reads Netflow ver.9 can be enabled on Cisco GSR 12000 Series, but no mention about catalyst switches. So, I ' m curious about that Netflow ver 9 can be activated on catalyst 6500 series.. because the point where switch is located already have mpls encapsulated packet ( mpls vpn packet).
Thank you , in advance.

NetFlow is now integral to Cisco 6500. A configuration we recommend is as below:
mls netflow // This enables NetFlow on the Supervisor.
mls nde sender version 7
mls aging long 64 // This breaks up long-lived flows into (roughly) one-minute segments.
mls aging normal 32 // This ensures that flows that have finished are exported in a timely manner.
mls flow ip interface-full
mls nde interface
The next two commands will help to enable NetFlow data export for bridged traffic which is optional. You can specify the list of VLANs here to enable bridged traffic.
ip flow ingress layer2-switched vlan
ip flow export layer2-switched vlan
Apart from this, NetFlow has to be enabled on the MSFC using the below commands.
ip flow egress // This command has to be executed on all the L3/VLAN interfaces.
ip flow-export destination {hostname|ip_address} 9996 // The hostname or IP address of the flow server
ip flow-export source {interface} // The interface through which NetFlow packets are exported. eg: Loopback0
ip flow-export version 9
ip flow-cache timeout active 1
snmp-server ifindex persist
The new Cisco Flexible NetFlow actually allows for export of MPLS specific information (I believe it is stack lables) in addition to information on IP Address, port, etc. But you will need a tool that can support these additional fields. Otherwise you can view IP, port, protocol, etc related information from MPLS links.

Can you tell the IP address of a device attached to a 6500 Catalyst Switch

I have devices attached to a Catalyst switch, and I wanted to find out which device is attached where by checking the IP address of a specific device attached to a port. The ARP tables don't show any devices. Anyone know a quick/dirty way to do this?

The arp table on your switch does not show this as the switch does not talk to devices directly and thus does not need this information. Do this:
- From the switch ping devices you want to find where attached to.
- type "sh arp" on the switch. This time it will contain the information you need.
Similar to this:
switch6500> (enable) sh arp
ARP Aging time = 1200 sec
+ - Permanent Arp Entries
* - Static Arp Entries
10.0.0.1 at xx-xx-xx-xx-xx-xx port 1/1 on vlan 15
10.0.0.30 at yy-yy-yy-yy-yy-yy port 1/1 on vlan 15
switch6500> (enable) ping 10.0.0.20
----10.0.0.20 PING Statistics----
5 packets transmitted, 5 packets received, 0% packet loss
round-trip (ms) min/avg/max = 1/1/1
switch6500> (enable) sh arp
ARP Aging time = 1200 sec
+ - Permanent Arp Entries
* - Static Arp Entries
10.0.0.1 at xx-xx-xx-xx-xx-xx port 1/1 on vlan 15
10.0.0.30 at yy-yy-yy-yy-yy-yy port 1/1 on vlan 15
10.0.0.20 at zz-zz-zz-zz-zz-zz port 3/22 on vlan 15

SNMPv3 on Cisco 2960-S Switch to NCS

TCP delay on catalyst switch

i experienced a TCP delay on catalyst 4506, avoid the problem when i replaced 4506's with dummy unmanaged switches.
i used two PCs(PC 1 and PC 2) and two 4506 switches (S1 and S2)
PC 1 is connected to S1 (fast ethernet port)
PC 2 is connected to S2 (fast ethernet port)
S1 is connected to S2 (SFP gigabit ethernet port)
-I started continuous UDP,TCP,MULTICAST and PING from PC1 to PC2
-I unplugged link between Switch 1 and Switch 2
all communication stopped.
-I plugged link between Switch 1 and Switch 2
-UDP,MULTICAST and PING started immediately but TCP started with approximately 15 seconds delay. :-(
I repeated same procedure with unmanaged dummy switches instead of 4506, there wasnt 15 seconds delay. TCP showed up in 1 second.
How can I avoid TCP delay on catalyst switches? Probably some tuning with configuration would do the job?
tx for helping

hi gp and thank you very much for responding to this unusual problem.
- switch ports to the PCs are configured as portfast.
- switch ports between two catalyst switches are not configured (default)
- i didnt use the 'switchport access' command since they are default layer 2 interfaces. would 'switchport access vlan 1' command make any difference?
- i looked at the port status and confirmed connection is 100 mbps full duplex.
unusual issue is; ping, udp, multicast shows up in a very short time after I re-plug the uplink. that proves all ports are in forwarding state. only TCP shows up with delay, which doesnt occur on 200 $ unmanaged switch??
thanks in advance for any suggestions

Can a Catalyst switch terminate a QinQ (double vlan tagged) connection on an SVI?

Can a Catalyst switch terminate a QinQ connection on an SVI? Is anything similar possible?
I know I can pass through QinQ traffic through a switch at L2, but can I take it in at L2 with double tags and terminate it on a L3 SVI somehow?
Im looking for a simple way of making a WAN lab environment.
IE I want to do the equivalent of this on a Catalyst such as a 3560/3750:
interface GigabitEthernet0/0.1
encapsulation dot1Q 101 second-dot1q 1
ip vrf forwarding 100101
ip address 1.1.1.1/24
interface GigabitEthernet0/0.2
encapsulation dot1Q 101 second-dot1q 2
ip vrf forwarding 100102
ip address 2.2.2.2/24
thanks in advance.

Differences between MSFC1 and MSFC2 in Catalyst switches

Hi,
Want to know the differences between MSFC1 and MSFC2 in Catalyst switches.

Hi,
There is not much difference between MSFC1 and MSFC2, the main difference is how the MSFCs send the hardware programming to the PFC. The MSFC1 uses MLS to program the hardware by using the first packet of the traffic. While the MSFC2 uses CEF-based MLS to program the PFC so that the supervisor can make the hardware switching of the packet. NOtice the difference if the MSFC1 needs to see the first packet while the MSFC2, in theory will not need to see a first packet as it uses the CEF routing table to program the PFC2. Now, the kicker, if MSFC2 in sup1A , all this CEF-based MLS is not used since it needs PFC2 to be able to do this. Sup1A does not come with PFC2 only Sup2 comes with PFC2. The MSFCs gives the Cat6K a L3 ability and it's important but the switching performance of the switch depends on the PFC.
Here is a link on MSFC2 data sheet:

Dacl on ACS 5.1 and Catalyst switch 3560

Dear all
I have ACS 5.1 and Catalyst switch 3560 with version 12.2(53)SE. I configure a dacl on the ACS and I use it on authorization profile.
This authrization profile is used on access policy.
I tried the authentication but it doesn't work. I checked the ACS logs and I found that the user is authenicated successfuly but the dacl gives this error (The Access-Request for the requested dACL is missing a cisco-av-pair attribute with the value aaa:event=acl-download. The request is rejected)
Steps:
11001 Received RADIUS Access-Request
11017 RADIUS created a new session
11025 The Access-Request for the requested dACL is missing a cisco-av-pair attribute with the value aaa:event=acl-download. The request is rejected
11003 Returned RADIUS Access-Reject
DACL:
deny ip host 1.2.3.4 1.2.3.0 0.0.0.255 log
permit ip any any log
Thanks on advance,

Dear Tiago
I applied the command "radius-server vsa send". Now I can see the dacl is applied but I can't see it on the switch and even the authentication is succueeded ont the ACS logs but it give me unauthoized on the switchport. You can see the logs( started with the username acstest and the access-list is applied but it doesn't work and you can see theat it goes for mab after eap timed out). I hope you can help on this issue.

Cryptographic IOS versions on Catalyst Switches

1. Where can one find the differences between Catalyst switch IOS with cryptographic features and without cryptographic features?
2. In order to access Cat switches over SSH and HTTPS, do we require Cryptographic versions of the Cat IOS?
3. What does "k9" stands for in IOS names? e.g. "3560-ipservicesk9"
Thanks

Hi
Answer to Q1 :
Best plase to compare the Catos and IOS is
www.cisco.com/go/fn
there you can search by ios names or platforms or features and compare images.
Answer to Q2 :
Yes you need Cryptographic version
Answer to Q3 :
K9 stand for Cryptographic version if you have ipservicesk9 you can do SSH in the feature navigator if you search the ios without K9 you will find this :
IP SERVICES W/O Crypto
that means this catos does not support Cryptographic.
