Re: Ask the Expert: Access LAN Switches (Cisco Catalyst 4500E, 3

Hi Nikolay,

Are there any plans to release a 40 Gbps blade for the 4500E now that the technology is available for the Nexus 7K and 6500 range of switches?

Thanks

Hi Sean,

It is planned yes, but unfortunately I have no exact products or dates to share. Current fabric provides 48 G per slot so for 40G port we can provide only single non-blocking port. I guess it will come with next fabric to have at least 2 non-blocking 40G ports in same card.

Hi Nikolay,

This question has come up here several times, and we have had different dates from Cisco as to when and what IOS will support VSS for the 4500 series. So, can you provide us the latest on this?

Thanks,

when and what IOS will support VSS for the 4500 series.

Hi Reza,

I've seen a Cisco presentation that states that end of 2012 to mid-2013.

Hello Guys,

It is planned in  new feature release 15.1(2)SG, XE 3.4.0SG along with ISSU. Unfortunately no exact date set and I agree with Leo that those should be in range end of 2012 to mid-2013. We just had one new release  XE 3.3.0SG, 15.1(1)SG on CCO.

Sorry Reza, I ain't THAT good.

Nik's probably the best source.

I'm suspecting it could be a 4.X.X IOS number.

Alot of people who's purchased the Sup7E and the 4500X would be keen to know the release date.

Re: Ask the Expert: Access LAN Switches (Cisco Catalyst 4500E, 3

Hi Nik,

I have another future release question.

When searching for an IOS for the 4510 I couldn't find any that supported OSPFv3 authentication with IPSEC.

Did I miss one or is this a feature that will be released in the future? If so do you have a timeframe?

Thanks

Hi Nikolay,

We work on a huge LAN, and one of the responsibilities I have is port security. 

If I go through one of our switches and any port isn't connected my job is to shut it down.

Currently I use #sh int count to verify that nothing is on that port, and it is safe to shut down with interfering with a user, (who just happens to have their computer off)

The problem I am running into is that I have not found a proficient way for me to see only ports that have 0s only on their In and Out packet count.

The pipe command hasn't proved to be very useful in this case, and I was just hoping for a very practical tip in this.

Thank you

Hello Chai,

Not sure if I understood your question correctly but I think you need a command which will show you only the interfaces with 0 In and Out packets.

Well pipe should be working here. The only thing is to build the best expression for it. After pipe you can use different regular expressions. See more about it here:

http://www.cisco.com/en/US/docs/ios/12_2/termserv/configuration/guide/tcfaapre_ps1835_TSD_Products_Configuration_Guide_Chapter.html

I was just playing in my lab and came with the following one which match 0 in the middle coulmns of "show int counter":

sh int count | i _0_.|In|Out

it gives smth like:

HTTS-VSS#sh int count | i _0_.|In|Out

Port                InOctets   InUcastPkts   InMcastPkts   InBcastPkts

Te1/1/1                    0             0             0             0

Te1/1/2                    0             0             0             0

Te1/1/3                    0             0             0             0

Te1/1/4                    0             0             0             0

Gi2/2/1                    0             0             0             0

Gi2/2/2                    0             0             0             0

Gi2/2/3                    0             0             0             0

Port               OutOctets  OutUcastPkts  OutMcastPkts  OutBcastPkts

Te1/1/1                    0             0             0             0

Te1/1/2                    0             0             0             0

Te1/1/3                    0             0             0             0

Te1/1/4                    0             0             0             0

Gi2/2/1                    0             0             0             0

Gi2/2/2                    0             0             0             0

Port               OutOctets  OutUcastPkts  OutMcastPkts  OutBcastPkts

Gi2/2/3              2013885             0          4840             0

It is at least excluding interfaces which had 0 only in last column. You can play with expression to build your own which matching your needs better.

Hi Elguen,

Basically you will not be able to add static route for this subnet because you have alredy that network configured on the interface Ethernet0/2. This automatically adding that route as connected to the routing table.

I'm not the expert in ASA thus might not be the best resource to answer you in more details. I recomend you to open you query in our Security forum:
