I am working for a customer on an enterprise site containing many 6509's. We have built a test environment and upgraded a chassis from sup720 running 12.2(18)SXF15 to VS-S2T-10Gb running 12.2(50)SY on the management card. I have noticed and so has the customer that there are many commands missing or added and they want an expalnation of these. I can do some of them easily, change syntax etc but for instance it has added a table-map, 50 vlans with a large MTU and large COPP policy.
What are these ?? and also is there a quick way resource etc to find out why the commands have been added/removed, for instance-mls ip cef load-sharing full is missing--
We replaced a 3560 with a new 2960S and I'm only able to configure a single ip sla where before we had three ip sla entries on the 3560. Obviously, one is a L2 switch and the other a L3 switch. This is an expected difference between switches, correct?
View 6 Replies View RelatedWe are looking to replace some aging 3560 switches with 100Mb/s interfaces. They service IP phones and workstations.
For having IP phones directly connected to access switches that are also servicing workstations, we don't need L3 routing except in the core, so the question is what would we lose if we used 2960S switches for access switches.
I understand from having spoken with Cisco TAC that a limited subset of QoS is available on the 2960S platform. Does that includes the priority queue that is enabled when you turn on mls qos on a L3 switch?
I am trying to decipher the differences between the two models of the 1921 router. One has an IP Base IOS and the other has a Security IOS. I have an ASA so I don't think I need all the Security IOS bells and whistles on an internal router. Although, does the IP Base IOS allow for trunking and sub interfaces? I definitely need that and on CDW's website it says that the 1921-Sec/K9 w/ Security IOS includes 802.1Q and that spec is not listed on the 1921/K9 IP Base IOS model.
View 3 Replies View RelatedI am setting up my 2nd 1811 router for NAT and VPN. The 1st 1811 works great, completed a few months ago. On this 2nd 1811, I decided to just copy the working startup-config from the good, 1st router to this 2nd, and then change IPs and from there. I did not do the setup wizard, but just erased the startup-config, reloaded, gave temp IP on local LAN and copied good startup-config from TFTP server.
Question: on this 2nd 1811, I show this:
mmi polling-interval 60
no mmi auto-configure
no mmi pvc
mmi snmp-timeout 180
no ip subnet-zero
I do not have this on the 1st, and I cannot get rid of it. Is this due to IOS versions?

I understand that my questions seems to be rather strange cos supervisors is rather old (Sup1A especially). But i am interested in understanding what puprpose were in production SUP32. I cant find out enough differencies between Sup1A with MSFC2 and Sup32 to understand what reasons lead to deploying new sup in none fabric supervisor series.
Both supervisors have same perfomance - 15Mpps and have limitation on backplane bandwith of 32 Gbps (cos both use swithing bus), both supervisors equipped with MSFC2 and etc. Differencies i found:
SUP 32 have 10Gbe ports support (but this seems to be doubtful enhancement - with it perfomance GE ports seems to be more appropriate technology isnt it?) SUP1A equipped with PFC, SUP32 with PFC3BSUP32 deploys CEF (what is benefit of CEF if perfomance same?)

I'm currently trying to get up to speed on a 1941W ISR. I belive i have most of the configuration correct based on reading the documents on this site. However, i'm noticing that my lan to lan network performance is very slow. Peaking out about 3mbs. I was reading some documentation that suggested MGF (MultiGigabit Fabric) might resolve this problem.
I have a basic setup in my test environment trying to emulate a branch deployment. 1941W connected to a access switch (3400).
- I'm getting slow perfomance (thoughput) between the vlans 66,30,10. Will MGF fix this problem? How do i configure it?

I currently work in the IT field part-time as a end-user support technician while I am finishing my Bachelor's Degree in Network Administration. I'm not completely new to networking at this point, but I am by no means a master of it either. The basics of small networks (less than 10 PCs) and the lower-end of small business grade Cisco equipment are not unfamiliar to me. Up until this point however, I have had very little experience with any higher-end Cisco networking equipment.
Now on to the questions, which may seem like the answers should be obvious, but let's face it, I do not have the resources to own much equipment myself at this time for experimentation purposes, nor does the school I am attending have a lot of financial resources to provide us with recent hardware to learn on. What I want to know are a few things about PoE as implemented on Cisco devices, specifically the SG200-50P small business series switch. According to the technical documentation, the switch supports PoE on 24 of its 48 ports, specifically 1 - 12 and 24 - 36; simple enough. The switch is currently installed in an office that has less than 24 connected devices, but that is currently expanding. None of the PoE ports are utilized as of yet, but going forward, there will be more than 24 connected devices. Will another switch need to be installed if the additional connected devices (PCs and printers) are not using PoE, or is the PoE an auto-sensing feature that will simply remain disabled if a device that does not require power over the network cable is connected? Is there some setting that needs to be changed through the management interface to keep devices that should not be drawing power from doing so?
There will likely be some additional questions generated by my inquiry, and I fully understand if these are completely novice questions, but I admittedly do not know the answer. When I Googled it, I was greeted by a few hundred thousand results, the first dozen or so pages of results all being for places to purchase this particular type of switch, so I thought I would try my luck on the forums of the place that made it.
On a recommendation from a network engineer, I got a used Cisco 891. Having worked with small business routers most of my working life, I thought this should not be a problem. However, I had no clue these things used a console and command line to initialize. I have the console cable, am able to console into the device, but am haphazardly issuing command lines straight out of the PDF manual but cannot get Cisco CP to discover the device.
From what I can tell, I am stuck at the point where the manual tells me to enable http server. I ran the command lines several times, executed write mem where available, but when I run the show services command, http is not enabled.
And if you do refere to command lines, I was reading some other forums and they were speaking of "run this command, run that command" but I could not make out the correct syntax, in what mode, whether it be config or config t, etc. So I might need a wee bit of handholding.
I'm hoping that once I can get Cisco CP or CPE to discover the device, I can make my way through the GUI to configure since those usually do make sense to me. As of now, I'm in the thick of it ...
I am trying to configure a 891 W to basically provide DNS from my ISP to my internal clients on the 891 W. Currently when I am on a PC I can see that I receive my IP information along with the correct ISP DNS IPs. However when I try to connect or resolve a URL it fails. Nor can I perform an ns lookup from the cli of the 891 W. I seem to be having a translation issue with DNS.
View 2 Replies View RelatedI am trying to configure Cisco SG300-52 switch for the first time and stuck without CLI configuration option. The configuration can be done using GUI, however, configuring using CLI would be more comfortable (as I am used to work with CLI of other Cisco switches)..
I was able to lo gin to switch using SSH, but the CLI appears in MENU format and was not able to find any way to go to CLI mode.
As per some blogs, in SG300 switches CLI mode can be accessed using Ctrl + Z in Menu, which did not work either in my case.
Switch is running with latest firmware version Sx300 Firmware Version 1.2.7.76.
I have a headquarters office that has recently bought a new voice system.
We have a site to site connection from the head office to 3 remote offices. All have ASA5505 firewall.
I have created 2 interface on the ASA5505: 1: inside with vlan1 and switch port port12: voice with vlan100 and switch port port2
Port1 on the asa goes to port 23 on the switch for vlan data
Port2 on the asa goes to port 24 on the switch for vlan voice
Port23 is member of vlan1 data
I added vlan100 to port 24 but by default vlan1 is member and i can't remove it. Its greyed out
All ports on the switch are member of vlan1 and vlan 100 because the port on the switch goes to the phone and from the phone there is a port that goes to the PC. Phones are getting addresses, and PC as well.
I am having a kind of loop because there is 2 exit for vlan1 (port 23 and 24) and that's slowing down my system and sometime i loose the connectivity to my servers.
When i do a show arp on my asa, i do see that some IP are beeing learned on the wrong interface. some PC addresses 192... are on the voice and some voice IP 10.10... are on the inside.
I am pretty sure that the problem comes from my switch configuration.
I've goggled and searched here, and I can't seem to find what I'm looking for. I need to make a couple changes to a clients Cisco 800 series router, enable ping replies add ip addresses to the ssh ACL.I can't seem to find any basic commands for CLI anywhere.
