Cisco 300 series switches with 802.3at standard

I'm a bit confused as to which of the 300 series switches supports the 802.3at standard. According to the website, the SG300-28P supports it. But in the quick start guide for the 300 series, only the MP models (excluding the SF302-08MP and SG300-10MP) including the SG300-52P has it. Can someone give me a difinitive answer to this? Thanks!

LJ,
P = PoE capable. On the 300 series, half of the ports can provide 15.4W, or all can provide half that.
PoE+ is NOT SUPPORTED.
MP = Maximum Power. This means that all ports can provide up to 15.4W. PoE+ is supported on some models only.
PP = PoE Plus. Can provide up to 30W on a single port. Note the maximum PoE budget for each switch. Also,
half of the ports can provide 15.4W, or all can provide half that - any extra power used by PoE+
MPP = Maximum Power and PoE Plus. This means that all ports can provide up to 15.4W - any extra power used by PoE+
According to the Data Sheet:
"Switches support 802.3at PoE+, 802.3af, and Cisco pre-standard (legacy) PoE. Maximum power of 30.0W to any 10/100 or Gigabit Ethernet port for PoE+ supported devices and 15.4W for PoE supported devices, until the PoE budget for the switch is reached"
The PoE+ models are brand new and are not widey available yet. I did a web search for SG300-28PP and found that at least a few online resellers have it in stock.

Cisco 300 series switches

hi all
Ive looked through some of the online content but dont see a definitive answer to my question about the physical size of the switches, are they all 19" rack mountable or desktop?
I look forward to a confirmation..

Where is the 300 series switch with 48 gigabit ports and PoE?

Love the 300 series but surprised that Cisco did not put out a 48 port model with gigabit and PoE. Would love to hear from Cisco on the reasoning behind that and if there are any plans to introduce one? Given that gigabit and VoIP is the future at many companies it only makes sense.

The switches use the SFPs to link to each other. The SG500 has ports for 1G or 5G and the SG500X has 10G ports. Whichever port you select will be the speed at which the switches pass traffic and stack control information. These same ports can be 'reclaimed' if you were to set the switch to stand alone mode. I have put a chart below which details the ports you can use and the speed of these ports.

Scripting reboot for Cisco 300 Series switches

I would like to have some help putting together a script for rebooting our 300 series POE switches. I have about 150 at this stage to administer and it would make it much easier not to have to remotely reboot them. The IP settings will be the same for each location and we have about 2-5 in each location. I will be logging in through logmein to each remote server, and will run the scripts from this to the local switches. Any help would be appreciated.

I was playing with my Indigo on an SG-500 and it seems to work. Create a session for each switch and in the session properties for each switch enter your crendentials (user/pass) IP/port, etc, I was using telnet, port 23 for this and then under the send command tab, on connection I entered:
reload
y
One command per line up to 20 commands I believe and it connected, I saw my prompts and replies and then shutting down.
So if you try this you can just go down the file tree list for switches with cameras than need a reboot and restart the entire switch if you like, quick and easy.
You could also add a folder for each switch and a session in that folder possibly for each camera/port with online port number changing for each camera in the session properties and then selectively cycle power for just the affected cameras.
Example for port 22/camera xxxx:
conf t
int gi22
power inline never
power inline auto
It would take a fair amount of time to set up but once done you could just pick a switch folder and the port in that switch to cycle. If you have multiple port on a switch you could use
conf t
int range gi22-24
or
int range gi1,6,16,20
power inline never
power inline auto
might have to verify that syntax

Creating VLAN on our Cisco 300 series router

I am wanting to create separate VLANs on our Cisco 300 series switches, but I am struggling to find any decent examples out there.
Our basic infrastructure is
Router with
192.168.1.1 VLAN1
192.168.2.1 VLAN2
The switch is set up on ports 2345 for VLAN2
Port 1 is attached to the router on VLAN1 and VLAN2 assigned.
My problems seem to be that I really not sure what settings I should be using for each the ports to get this to work correctly

Hi,
Hope below link will have the information which you are looking for.

If you are looking for only vlan creation then below link will help.
http://sbkb.cisco.com/CiscoSB/Loginr.aspx?login=1&pid=2&app=search&vw=1&articleid=80
According to your above description you have connected the router to port 1 of switch and you have configured it as vlan 1...Should this port be trunk???

Are 300 Series switches compatible with pre-standard PoE detection in old Cisco phones?

Are 300 Series switches compatible with pre-standard PoE detection in old Cisco phones? They don't seem to be (a 7902G won't power on when connected to an SF302-08MP with firmware version 1.1). Is any special configuration needed on the switch to enable this detection?

Please note that the 200 and 300 Series switches now support Cisco Legacy POE as of September 2011, allowing it to deliver power to 7960, 7940, and other pre-standard phones and APs. Details provided at the following link:

Using TACACS+ With ACS 5.6 on 300 Series Switches v1.4

I was wondering if anyone could give me instructions on how to set up ACS for TACACS+ on a 300 series switch using Authorization? I can get it to work to authenticate, but the authorization doesn't seem to work like a catalyst switch. Thanks in advance for any help!

Brandon, thanks for the link, but this is for the older software before they included authorization (the v1.4). I've looked through a bunch of manuals and tried to find examples online, but it doesn't seem like anyone has anything out there I can find.

Cisco 500 series switches

Dear support,
Can Cisco 500 series switches deliver 24V on the access port for POE operation?
Best Regards

I belive the 802..2F and 802.2at poe standard is strictly 48v. I haven't found anything to the contrary. There are inline convertes 48v-24v or something like this that can be used with a non poe switch: http://www.digital-loggers.com/poe24.html but that means all conected device would be off the same access port / vlan.

Cisco MDS series switch details

Hello I 'm new to CISCO Switch world.
I 'm working as Clariion Admin and have have taken up the responsibilty to manage switches.Since,i am a novice i need little guidance on how work on cisco switches.I know the Zoning (how zoning done on MDS 9000 series switches) part ,but would like to venture deep into the details on CISCO MDS series switches.
Like, the use of Port channels etc.
Will really appreciate if some one can help me with a link or place ( not the configuration guide) where in i can find details on concentrated more on the theory part .
Thanks in advance!

Actually the best info is in the configuration guides. There are some external companies that run training sessions on the MDS to provide in depth training. There is the MDS cookbook available on CCO that is also a good point of information. If you search on 'MDS white papers' after you login into Cisco.com, there are several good documents that might meet your needs.
Hope this hels,

Firmware upgrade question for 300 series switches

Hi-
I have a customer that is investigating a strategy and solution for centralized firmware management of the 300 series switches. They have found an issue in the lab where they were trying to roll back the firmware to a previous version They can not roll back to the previous firmware version, which is desirable in the case of finding an issue in the new firmware that causes them to have need to rollback to a known working version.
We have read in the cisco 300 switch admin guide that there are two images (active and inactive) and that a new downloaded firmware always replaces the inactive image and is active until explicitly set. The admin guide does not mention inability to make an older firmware image as active image when the switch has previously run on a new release firmware image. My customer's engineers testing have informed me that an older image can not be made active after a newer image has booted. Can you please verify if this if a fallback is supposed to work as it is causing a lot of concern-
Thanks-
Jena

Major Changes and Defects Corrected
• Hardware version 1.0 devices that were upgraded to software version 1.1
can now be downgraded to software version 1.0. You must delete the
startup configuration file before rebooting the device to software version
1.0. Otherwise the device may have problems when booting up. You may
backup your running configuration before the reboot, and re-import the
configuration afterward. Major Changes and Defects Corrected

CCA for 100 + 300 series switches?

Is it in the roadmap to provide CCA control over 300 series switches? We have a lot of SRW2008's put in before the 8-port ESW existed...and we have PITA vlan consistency issues out there too that I think CCA would help fix.
While I understand the "don't pre-announce products", I need a level of design intent around CCA - is it a tool for configuring UC series pieces primarily and all else is secondary? Or is it the multi-device config tool for all SBCS pieces?

Nothing to do with the UC - primary concern is standalone networks.
Real life case:
2 ESW switches in control room hooked up to SA540
Closet switches are SRW2008's
Port no more than two devices are supposed to go now has 4, add an SRW2008 to the desk location.
Now, it turns out that there is a badly behaved device at the desk - a video player that spews all sorts of traffic when it's playing that doesn't play nice with others. So I now need to set-up a VLAN crossing those two switches. Oh, and it turns out the customer decided to unplug an access point and plug it into that switch too which ended up causing a loop when the PC plugged into ethernet someplace else attached to the PC.
Tasks:
Ensure that the 2 SRW2008's have proper vlan assignments to setup a port vlan for that video server.
Issues:
Make sure you assign proper configs to both ends of each link
Make sure not to confuse one SRW2008 with another
If new vlan, make sure all other ports that need to see it can still see it.
Applications for CCA:
Visualize all VLANS
Document port assignments (i.e. where is the video server vs. printer on that last leg 2008)
More easily see port statistics across multiple switches
So after I did that work, I realized that the SA540 wasn't really up to being an aggregation switch too and made the ESW-540-48 into the aggregation switch which required some more changes - however CCA made it easy...
At another job, I have SA540 + AP541ns (upgraded from RVL200 + WAP54GP's) but if I had 300 series in CCA, I'd upgrade the SRW2024's and SRW2008's but without easy management tools, the labor cost will be too high to make their networks really managed.....CCA makes that layer of management cheaper.

Cisco 300 series: my PCs cannot reach the 2nd subnet

Dear Community/Support:
setting up our new series 300-28 in Layer3 Mode with a very basic network setup:
LAN: 192.168.0.0/24
VOIP Switch: 10.128.0.1 -- attached to GE24
default VLAN1- 192.168.0.254
added IPv4 Interface: GE24-10.128.0.254
which added the IPv4 route to the subnet 10.128.0.0
which added the ARP entry for 10.128.0.1
so in the admin interface the 300 can ping 10.128.0.1,
but my PCs in VLAN1 cannot reach it at all.
300-28 has DHCP enabled, IP Range 192.168.0.9-99/24, Gateway 192.168.0.254
Help Please,
i simply fail to understand why :(

Sorry I don't really know the 300 series range of products. On other devices you would need to enable IP routing.
Have a look at this link it talks about changing the system mode to layer 3?
