Cisco Switches :: SG200-08 And SG200-08P Fail To Hold Or Update Date / Time

May 24, 2011

SG200-08 and SG200-08P fail to hold or update Date/Time.(New installation for a UC320 setup.)I've got both an SG200-08 and SG200-08P that are failing to maintain date/time when set with "Use Local Settings".  Every restart/powercycle causes them to reset to Dec 31 1969.  Other settings save fine.I first tried to set time via SNTP Unicast using a variety of public time server addresses including the 3 hard coded to the SG200-08 firmware:
 
Sadly though it always just shows  "Active Server  Server Host Address: 0.0.0.0"  and continues having 12/31/1969 as the date.  Both after a config save and a reboot.I can ping the NTP servers just fine from the switches either by IP or by hostname.At this point I've decided that I must be missing something simple. At least I hope so... otherwise it's a firmware bug which means waiting for a fix.Other devices behind the same firewall/gateway (RVS4000) are updating NTP

Cisco Switches :: SG200-18 To C2960S Trunked - SG200 Cut Off The Net

Apr 29, 2012

how to connect our new SG200-18 to an existing Cisco network, in particular a C2960S.Here's what I've got:
 
<----- Rest of network ------- C2960S ----------- SG200 ----- (PC connected directly to the SG200)
 
On the C2960S-side here's what I've got on the corresponding interface:
 
interface GigabitEthernet1/0/1
switchport mode trunk
 
On the SG200-side I've set the IP-address and default-gateway accordingly, however:From the SG200 I can't ping any other host on the same IP-subnet as the switchFrom the SG200 can't ping the default-gatewaycan't ping from any other host or the default-gateway *to* the switch But:On the SG200 I've got plenty of MAC-addresses under "Dynamic Address Table" - however only MAC-addresses that belong to the management-VLAN of the SG200 (i.e. VLAN9 in my case)The MAC-address table on the SG200 even includes the MAC-addresses of hosts on the same VLAN I tried to ping without success. For example: I tried a PING from a host having a MAC-address of 00:19:bb:31:91:30. This MAC shows up in the arp table of the SG200. To cross check I connected a dedicated PC to the SG200 and assign it an IP-address out of the management-LAN-range of the SG200 - in this case I can access the switch (i.e. PING, WEB etc.)So to summarize: Connectivity is OK when going from directly connected devices to the SG200. No connectivity from devices that are behind the C2960S towards the SG200 and vice versa. (The problem is definitely not with the C2960S-side since we've got plenty of them hooked together without problems.) I'm enclosing the screenshots of the corresponding definitions on the SG200.

Cisco Switches :: Very Slow Transfers Between SG200-18 And SG200-8?

Apr 16, 2013

I'm baffled by the poor performance that I'm seeing when passing traffic between my two Cisco SG switches.
 
The configuration is as basic as I can make it, no VLANs, QoS or bonding.  Both have been updated to current firmware as part of the troubleshooting process.
 
When I transfer data within one of my switches I see 50/60Mb/s. When I pass the same traffic between both switches I see 0.6 Mbs/ or less.
 
I have tried to eliminate every possible factor including switching out the cables.  No success.

Cisco Switches :: Virtual NIC On VOIP System And SG500X?

Aug 27, 2012

We have a VOIP system with 1 physical NIC attached to our SG500X. It has a virtual MAC address along with the physical MAC address. It has 2 IP addresses tied to it.
 
I can ping the physical IP address, but can only ping the virtual address from the same vlan as the virtual nic. However, if I clear the arp table, a few pings will go through until they all time out again. This is causing problems on my phone system, and I need to establish this communication. I have tried putting in static MAC and ARP entries, but that does not work.

Cisco Switches :: SG500x How Many 10GE Ports Can Be Used For Uplink

Apr 25, 2013

i was checking the datasheet of 500X series and got confused regarding the 10GE uplinks. how many 10GE ports can be used for uplink and which transceiver should be used for 10GE copper uplink? for example, SG500x-24 switch has 24GE ports and 4x10GE uplinks. can i use the 4x10GE ports for uplinks or only 2 ports are for uplink and the rest for stacking?

Cisco Switches :: SG500X-24 Stacking - Keeping Connections Active

May 12, 2013

I am installing a network that has two SG500X-24 switches as core and several SG300-52 switches as access switches. I've seen in the SG500X-24 datasheet that there is a True Stacking feature. But in the data sheet there are not a lot of details about it. My doubt is the following. If I configure the two SG500X-24 switches as a single switch through stacking them, can I connect one SG300-52 switch to these two SG500X-24 switches through two cables (both configured as a LAG in the SG300-52 and in the SG500X-24 stack, one cable per SG500X-24), the  the first cable connected to the first SG500X-24 switch and the second cable connected to the second SG500X-24 switch and keep both connections active?

Cisco Switches :: SG500X 10Gb Copper To Server Hardware

Feb 7, 2013

We have a site with a number of SG500X switches who are about to have a new server installed.
 
The server is a Dell ESXi host with a dual port 10Gb NIC supporting SFP+.
 
I know the primary purpose of the 10Gb ports on the SG500X is for stacking etc. but the switch does come with four 10Gb ports.
 
Why I wouldn't be able to utilize a 10Gb port as a copper connection to the 10Gb NIC on the server? Anyone out there with a SG500X connected directly to a server at 10Gb?

Cisco Switches :: SG200-18 Switches With LC Single Mode Fiber SFP's

Dec 2, 2012

We have a project in which we are using 34 Cisco SG200-18's each with a MGBLX1 (LC Single Mode Fiber) SFP mini-GBIC.All the fiber's come back to one building where we must "bridge" all 34 fiber connections. What hardware should be used to accomplish this? A L2 switch? For example, a 12 port SFP Switch with Fiber SFP's accepting the first 12 fiber connections, then other switch with SFP for the next 12 and so on, until there is a overall capacity of 36 and having patch cables between the 3 switches?
 
what cisco or non cisco hardware would work with these SF200-18's to accomplish this?

Cisco Switches :: Replacing Some Netgear Switches With SG200

May 16, 2012

We are replacing some netgear switches with the Cisco SG200.  The situation is relatively straightforward.  We have a series of VLAN's coming in on a trunk from a service provider for our Metro Ethernet locations.  These trunks then get cross-connect to various location for connectivity.  The problem we have is there are two VLAN's that need to go to the same switch which provides access to our public IP block.
 
I set up the two VLAN's on the SG200 with the trunk port VLAN tagging on the service provider port.  Then I set up a separate port for untagging the traffic with the PVID of the respective VLANS's as follows: [code] The public switch has no VLAN's configured (it is an SG200 too).  If I connect GE2 to the public switch everything works fine.  When I connect GE3 to the public switch, things die.  I thought this might be caused by STP although STP should not be detecting issues like this across separate VLAN's.  Disabled STP, no change.The same configuration with the Netgear worked without an issue.  FYI, the VLAN's cannot be changed...they are defined by the service provider in this particular case.  otherwise we'd just make them the same..

Cisco Switches :: ASA5505 - Does IOS Like CLI Exist In SG200 Switches

Aug 28, 2011

I need to purchase a few Gigabit PoE switches for a small business and I am thinking that SG200 or SG300 switches are perfect for this purpose.
 
Layer 3 functionality in SG300 switches is not great - HSRP or any other next-hop redundancy protocol is not supported, dynamic routing protocols are not supported, policy-based routing is not supported, etc. I may get one SG300 switch for inter-VLAN routing so that I do not have to send traffic to a Layer 3 device for this purpose, especially because my Layer 3 device (ASA5505) has only 10/100 Mbps interfaces. All other switches in the network don't have to be Layer 3 switches, and I am thinking of perhaps getting SG200 instead of SG300 swithces. However, because I am a long-time Cisco engineer, and know ins and outs of the IOS CLI, I would much rather administer the switches with CLI rather than GUI. So, do SG200 switches provide CLI (even if it is not officially supported) or is the only Small Business switch platform that supports CLI SG300? I do realize that the OS running on these switches is not IOS, but after having reviewed the CLI manual for SG300, I would say that 90+% of commands are identical to IOS CLI commands.

Cisco Switches :: CLI Access To SG200 Switches?

Cisco Switches :: SG200 Vlans Across Two Switches

May 22, 2011

I am trying to set up three vlans across two switches. The switches are Cisco SG200 and SG 300 series. There are 20 devices connected to the two switches including a router for Internet. Among these devices are five wireless access points all hardwired to the LAN. If I understand correctly the first thing I have to do is aggregate the two switches. I ran two cat5 cables to ports 1 and 2 of each switch. As I understand it all I need to do is to create SAG with the two ports on each switch. I think I need to use tagging but I don't really understand how to do this. Once I get the trunking set up correctly I want to create one vlan to which all devices will belong for Internet access. The other two would be for data and VoIP. Do I create vlans with the same name on both switches? When I assign the devices (by port) do I need to enable tagging? Which type of port setting should I use? I am assuming that by including the acess points in the vlans will mean that any wireless device connected to them will have acess to the Internet and the devices in the same vlan.

Cisco Switches :: SG500x Point To Point Connection Very Slow After 1.30.59 Update

May 1, 2013

I have a point to point 100mb line connecting SG500x switches at 2 locations, with these ports in a vlan together. I use layer 3 on the SG500x's to route between the two sites. I also have RIP protocol enabled to allow for automatic failover if the point to point fails (this works well).
 
I upgraded the ios to 1.30.59, and the connection now runs at a fraction of the speed. I have hard-coded the ports to run at 100mb full duplex, but I still only get around 12mb of throughput between the switches. I used to get about 90mb before. The provider also hard-coded the circuit to 100mb full duplex. The provider has checked the circuit remotely, and everything looks fine. I tested with a laptop at each side, and did get almost 70mb throughput. I would think this indicates some type of setting mismatch, but i cannot find anything.
 
I am using a backup vpn for now as some things look flaky as well (on vpn, I can use the web interface to access the SG500x on the opposite side, but on the point to point I cannot - I can ping the device though).
 
I have seen some references on here to shutting off STP on these 2 ports.

Cisco Switches :: SG200-50P - Devices Not Get POE

Jun 23, 2011

I just purchased a SG200-50P switch to replace a WS-CE500-24LC, that had a limited amount (4) of PoE ports.  I was running Cisco 7940 IP Phone, Cisco AP1231 and AP1100 series access points via PoE off of this switch.
 
When I attempt to plug in these device types into the SG200-50P they do not power up.  What is going on?  Why do these devices (7940 IP Phone, 7960 IP Phone, AP1100 series access point, AP1231 series access point) not get PoE from the SG200-50P switch?
