Telnet Cisco SF300-08

Hello guys...I just bought this switch last week.I tried to telnet this swtich using my laptop(windows 7 64-bit),but i failed.I suspect that this problem came from my laptop because i dont change any default ip setting of the switch.
There are 2 things that ive tried to solve this problem:
1) Start --> control panel --> Programs --> click "turn windows features on or off" --> tick "telnet client"
2) Start --> search "services" --> telnet --> startup type "automatic"
but stil I cannot telnet the switch. The error is "could not open connection to host on port 23: connection failed"
Please help me. Thank you

Hi Hafiz, by default the switch does not accept telnet connection. Log in to the GUI then go to Security -> TCP/UDP services and check the box for telnet and apply.
If it doesn't work then, it's a problem with the computer.

Trunking on Cisco SF300 Issue

Hello Friends,
Issue: I have 3 Cisco SF300 multilayer switches, I have configured one switch as a core switch and changed the mode to Router (from layer2 to Layer3) and configured Vlans and DHCP pools accordingly, but when i am trying to connect another SF300 to this switch by using VTP it's giving error then i tried searching a solution and found that it does not support VTP protocol, can someone please help me on that, how i can connect other SF300 to this core switch by using trunking.
My goal is to connect the Switch1 and Switch2 to the CoreSwitch by using trunking so that CoreSwitch can advertise all Vlan information to Switch1 and 2. and PC connected to Switch1 & 2 on different Vlans can communicate to each other.
Network Diagram:
CoreSwitch fast-Ethernet port 1 to 8 are connected to Huwai Router Port 1 to 8 using a dedicated physical enter phase to connect each Vlan to the internet. using Nat overload. CoreSwitch's fastethernet Port 9 to 24 are disabled, gigabit port 1 to 4 are trunk port and allowed vlan are 11, 12,13,14,15,16,17 and 20.
Note: All 3 switches are in Layer3 mode.
CoreSwitch Gigabit ethernet Port1 connected to = Switch1 gigabit ethernet port 1
CoreSwitch Gigabit ethernet Port2 connected to = Switch2 gigabit ethernet port 2
Switch1 Gigabit ethernet Port4 connected to = Switch2 gigabit ethernet port 4

How to setup a static multicast ARP entry with Cisco SF300-08?

We're running a cluster in multicast mode as a loadbalancer.
We have Cisco SF300-08 and when we adding a static ARP entry results in an error message telling the user that the hardware address needs to be a valid unicast MAC address.
So how to setup a static multicast in Cisco SF300 or maybe someone know other solution to setup multicastes mode in Cisco SF300.

Hi, Tom!
We have two watchguard xtm505(cluster active-active) in our network. Watchguard interfaces have one ip and one mac adresses. IP 192.168.111.1(Unicast) and MAC 01:00:5e:02:02:03(multicast). Cisco SF300 is router to outside networks(to internet). Cisco IP adresss is 192.168.111.254. There are another some hosts in this network.
Ping from hosts to 192.168.111.254 works well. Ping from hosts to 192.168.111.1 works well too. But there is no ping from watchguard cluster(192.168.111.1) to Cisco(192.168.111.254). And there is no routing to internet
This is well-known situation. We need to do following(example for cisco 3750):
1.    Start the Cisco 3750 command line interface.
2.    Add a static ARP entry for the multicast MAC address of the FireCluster interface.
Type this command:
arp arpa
For this example, type:
arp 192.168.111.1 01:00:5e:02:02:03 arpa
3.    Add an entry to the MAC address table.
Type this command:
mac-address-table static vlan interface <#>
For this example, type:
mac-address-table static 01:00:5e:02:02:03 vlan 1 interface gi1/0/11
But we can't add arp entry on Cisco SF300. CLI tells us "MAC address illegal"!
We tried enable igmp snooping, but is not helps.
Could you tell more detailed about MAC groups?

using export PATH=$PATH:/usr/ucb and try ... do it No, please don't. There is no compiler in /usr/ucb, and it is probably a very good idea to compile without /usr/ucb in your path. /usr/ucb/cc is only a wrapper to extend a very old SunOS compatibility environment onto an existing compiler.
If you don't have the current Sun compiler suite on your machine (go ahead and download it, it's free), then you can use gcc by invoking "perlgcc" instead of "perl" on the module's makefile.

Cisco SF300-24: Searching OIDs

Hello all,
I've got a Cisco SF300-24 and would like to monitor trough snmp:
- Memory Used, Free
- Interface CRC
- cpu utilization
- Memory Buffer Used
I checked your website related technical documentation for the Cisco MIB file, and the two species are listed below
•1.     Cisco Small Business 300 Series Managed Switch Administration Guide Release 1.2.5.PDF
•2.     SRW-US_v10_UG_A-Web. PDF
•3.     Sx300_MIB_1.1.2.ZIP
And I could not confirm that such OID values
Don't its hard to find the right OIDs.
Could someone help me please?
Thanks in advance

Hi,
I believe the device you mentioned is the IOS based device. If it is so then you may use following MIBs depending on the version of IOS.
Memory statistics via CISCO-ENHANCED-MEMPOOL-MIB and CISCO-MEMORY-POOL-MIB
http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a0080094a95.shtml

Cisco SF300-24 IP Configuration Issue

Hi,
I have purchased Cisco SF300-24 few days before. I have created 3nos of new Vlan. I am not able to assign IP to each Vlan.
When ever I aggign the IP to the next vlan, previouly assigned ip is not visible.
need help.

Hello,
Do you have the switch in Layer 2 or Layer 3 mode. In layer 2 mode the switch can have only one IP address. This can either be static or DHCP. The switch must be in layer 3 mode to assign IP addresses to each VLAN. Please see page 258 of the admin guide for how to set IP address for each VLAN. If you need to set to layer 3 please see page 61. Also, please make sure your device is on the latest firmware version 1.3.0.59. If you still have trouble try using a different browser. I tried this using Firefox and experienced a similar issue to what you describe. I switched to IE9 and it worked fine.
If you have completed these steps and are still having difficulties please call the Cisco SBSC at 866-606-1866 between 9am and 6pm your local time for further assistance.

VLAN trunking from Cisco Catalyst 3750 to Cisco SF300-48P issue and related

Hello expert,
I'm having difficulties to configure VLAN trunking between Cisco Catalyst 3750 switch with Cisco SF300-48P switch and my workstation unable to get any DHCP IP from our DHCP server via Cisco SF300-48P switch. Below is the snippet of configuration on both switches:
[Cisco Catalyst 3750 Switch]

description NCC-CC-1stFlr
no switchport trunk encapsulation dot1q
no switchport trunk allowed vlan 101-103

macro description switch
!next command is internal.

Are these are correct? Kindly advice!
Thank you very much!
Regards,
Alex

Hi Alex,
for the trunk port on Catalyst on port GE 1/0/45, we need to enable the trunk and for on encapsulation dot1q because this catalyst model is ISL capable also and the SF300 working only with Dot1q Encapsultion
The configuration on catalyst should :
#config terminal
#interface Gi 1/0/45
# switchport encapsulation
#switchport trunk encapsulation dot1q
#switchport mode trunk
#switchport trunk allowed vlan 101-103
#spanning-tree portfast
For SF300 the port trunk it looks fine but for the port where the PC should receive an IP address
#interface fastethernet29
#switchport mode access
#switchport ccess vlan 103
Please let me know after this configuration
Thanks

Smtp error in a cisco SF300

I have a problem with a SF300-24 24-Port 10/100 Managed Switch. I want to use the Switch Port Mapper of oputils (manageEngine) and it doesn't bring me the info of the switch such as: vlans, MAC and the IP address of the devices connected in each port.
I get this error inthe log of the switch. "%SNMP-W-SNMPAUTHFAIL: Access attempted by unauthorized NMS"
I have another switch of the same model and it works well. The smtp configuration is the same (it has an older firmware)
Any idea of how I resolve this problem?

Hi Slotmashines,
I would recommend you to reapply SNMP settings but if the error reoccurs please open ticket with Cisco Small Business Support team:

Uplink two Cisco SF300 swicthes through SFP

Hi,
I'm stuck in the following situation. I have:
Two SF300 Switches (SRW224G4P-K9-EU)
Two Gigabit Ethernet SX Mini-GBIC SFP Transceivers (MGBSX1)
Two 3 mtr Fiber cables LC -> ST (50FIBLCST3 StarTech)
Two ST Connectors (715297 st fiber connector)
The purpose is to use the SFP ports as an uplink between the two switches.
Now, using the SFP ports on both Cisco Switches, connecting through the fiber cable....it looks like the switches aren't connected. :-( Do I miss anything? The System Summary using the GUI control panel of one of the switches do not show any activaty on the SFP ports. Any help would be nice!

Hi Tim, if you want to prove the wire and SFP is any good, take a transmit and transmit (or receive and receive) end together in the same GBIC and connect it to one of the switch ports. This should make a loopback detect condition and the port should turn green with activity lights.
*Note, if the fiber has a clipholding the TX and RX together you may have to remove the clip or if the clip is fixed you may need to break it.

Finding rack mount kit for Cisco SF300-48P

I have a 10/100 POE managed switch laying around that I wanted to rack up to use for my VoIP phones. I however, had since lost the mounts (or never had them to begin with).
I've been looking all darn day for mounts just for this. It doesn't seem to fit any other of the 10,000 or so rack kits I have in house.
So far google and Ebay have been failing me. Everyone wants to sell me a darn switch, and I have that. I just want the bloody ears gosh darnit.
Can someone please, send me a model number I can search for on Amazon or Ebay to grab them?
Cheers,
Mike

If you are in the UK you could try ringing hardware.com.
They have supplied me with 'cisco-compatable' rackmount kits in the past at a fraction of the price of the genuine article.
Worth a shot.

Questions on Cisco SF300-24P

Does anybody in this discussion know if this switch supports any SFP's that use the
1000BASE-BX10-D and 1000BASE-BX10-U specs? The compatibility chart says nay but it can't hurt to ask.
I know it's a longshot.

Having said that, the switch model in the subject of this thread is an SF300 switch, which is only a 10/100 switch, so the answer is probably "no". Perhaps the SG300 switches, which are gigabit switches, might support what you are looking for.

Default/native vlan- voip data question- cisco sf300

hi everybody,
I have to set up voip and data vlans on cisco sf 300-24P. I will set up phones over LLDP and
on the same port (on switch) I will have untagged vlan 10 for data, so PC will be connected
through IP phones on network.
So what confuses me that on SF 300 under VLAN mgmt--> Default VLAN settings you got
options to change default VLAN id (which is of course VLAN1) which will be active after reboot.
How come that you can change default vlan? Isnt that default vlan is always vlan 1 and you can
change native vlan to be something else- let say vlan 10 which will be untagged vlan for data?
So what is best practise- should I just leave default vlan 1 and use it for data also or I sholud
change it to let say VLAN 10 to be native and use it for data.
And what will be with default VLAN 1 if I change it with above mentioned procedure?
Thx!

Hi,
Best Practice is to leave Vlan 1 for management purposes only. Create yourself a DATA and VOICE vlan. Usually Management vlan does not have DHCP enabled and have to static assigned pc within your management vlan for access. I would say that it really depends on how the rest of your network is configured depending on configuration of switch now. Unless this is a clean install.
Hope this helps,

GVRP not working on Cisco SG300-28

I have three Cisco SG300-28 switches. I setup a test lab environment with a core (server) switch in Layer 3 mode and the rest are (clients) in Layer 2 mode. As I understand, these switches doesn't support VTP, only GVRP. And GVRP works the same with VTP. Whenever you create VLANs on the core or main switch, other switches will learn from the core switch and no VLAN creation for the client switches will be made. (Hope I got it right. I guess GVRP is more complicated than VTP).
GOAL: Obviously, I want to use GVRP to create VLANs on the main switch so that I won't be doing it all over on the other switches.
The following is my (so far) configuration through CLI only:
I haven't use the web GUI. My SW version is 1.1.2.0.
1. I already enabled the GVRP globally.
2. I configured GE 12 & GE 24 as TRUNK ports for the core switch that connects both switches, I also configured GE 12 ports for both the client switches. All other ports are in ACCESS mode. (I am connected to GE 2 port)
3. I enabled GVRP on the TRUNK ports only for all switches.
4. I allowed all vlans on the TRUNK ports. (#switchport trunk allowed vlan add all)
5. All TRUNK ports registration mode is NORMAL and dynamic vlan creation is enabled on all trunk and access ports.
6. I created 3 VLANs without configuring its IP Addresses:
     vlan 2 = MGT
     vlan 3 = IT
     vlan 4 = MKTG
I don't know if I missed something on the configuration or the connection. I was expecting the vlans I created will be learned from other switches. Hope somebody can help me out. Thanks a lot.
QUESTIONS:
1. Is it necessary to enable all switches to layer 3 mode? Or depends on the network setup? Does this affect the GVRP?
2. Does switching ports to TRUNK mode means they are already 802.1q ports by default? Because I can't configure TRUNK ports to 802.1q (#switchport encapsulation dot1q) config like other switches.

trust me i am also heaving the same issue with my 3 Cisco SF300-24 ports ad i need the same what you was looking forward for...
can you please check my question and comment what i am missing :(
Aside to this i will try creating Vlans on my client switch without assigning the ip address as it's already assign and created on core switch.
Thanks,
Sandy
