Cisco Switching/Routing :: Auto-QoS On Catalyst 3750 LAN Switches?
Aug 12, 2012why the AutoQoS macro does not implement "priority-queue out" when configured on the 3750 platform running certain versions of software. The only other platform I have experience with AutoQos is on the 4500 and it enables priority queuing as expected. So what's up with autoqos on the 3750 on version 12.2(35)SE5?
When it comes to configuring QoS on campus user/phone access ports there are some important settings that can and should be considered but one can argue that enabling the priority queue is the single most impactful or important command. So I was very surprised and concerned when I didn't see priority-queue out. Cisco describes AutoQoS as a simple, quick way of deploying QoS on the LAN and it precludes you from having to learn all of the differences between hardware platforms. But is it true that this tool produces an incomplete config solution? Let me know if I am missing something.
Here is an example of what AutoQoS produces when applied to a 4507 with WS-X4648-RJ45V+E:(other interface commands are left out for simplicity)

Cisco Switching/Routing :: Catalyst 3560 / 3750 - Can Ping PC From Switches But Not From PC
Feb 19, 2013We have a couple of Cisco switches and connected a (Windows 7) laptop to one of them and it gets its IP address from a DHCP server.I can now ping the IP from all of the switches, no problem, also not when I log on to the core switch in the same VLAN as both notebooks. But from my (Windows 7) laptop, which is in the same VLAN as the target laptop, I cannot ping it.
I checked, default gateway is good on both sides, as are DNS servers.
Target notebook ---- Catalyst 3560 V2 switch === Core Catalyst 3750 switch (stack) === Catalyst 3560G switch --- My notebook

Cisco Switching/Routing :: Catalyst 6500 Supervisors Differences Sup1A Vs Sup32
Feb 16, 2012I 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?)
Cisco Switches :: SG500 Stacked Switches Getting Errors?
Dec 16, 2012We have 3 SG500-52 switches that are stacked and configured for layer 3 that replaced a couple of SG2010 switches a month ago. Switch units 1 and 2 are for servers and unit 3 for the workstations. The switches are connected with stacking SFP+ copper cables, 1 1M and 2 7M cables. The problems are occurring between the workstations and servers resulting in slow traffic on some links and connection failures. A repeatable failure occurs doing a backup from a PC on unit 3 to a server on unit 1 and 2 (2 port LAG). Moving the workstation to a port on unit 1 results in successful backups every time.
Initially I was able to confirm packet loss between my PC (on unit 3) and the servers using ping (ping -f -c 100000 -s 1460) of about .1%. The iperf program in udp mode also showed some packet loss and in tcp mode showed slow connections. A week ago I then upgraded the switches from v1.2.0.97 to v1.2.7.76 and rebooted. After that the ping and iperf tests show no problems although there are still slow connections to samba shares and the backups still consistently fail.
I suspect there is a problem with the stacking connections and have searched for traffic statistics on the stacking ports to look for errors but have not found anything. Doing a snmpwalk didn't reveal anything that I recognized. There are interface counters for all the ports except the stacking ports.
Cisco Switches :: SG500-28 Stackable Switches And NIC Teaming
Apr 17, 2012Am looking into using stacking and NIC teaming to create redunancy for user access to servers. What I am thinking is getting 2 SG500-28 switchs and configuring them in a stack that appears as one logical switch. Now on the servers I would configure 2 NICs to be a team so they appear as 1 logical interface, perferably in an active/active configuration using LACP. In this NIC team take 1 team member to switch A and the other to switch B, so each team member is on seperate switches.
Givent the scenario:
1) Will that work with the 500 series switchs? Reason for the switches is their price point is perfect for my client.
2) Besides the stack link will there also need to be a LAG between the switches or does the stack link do data traffic also?
Differences Between Two Models Of 3850 Switches?
Mar 4, 2013We are looking at doing some switch replacement. These switches will be in for ~7 years.We need POE for a VOIP phone system, and 10gb uplinks back to the core. We want to have the ability to go POE+ in the future.
We were quoted from our vendor for:WS-C3850-48P-S with 2x715w Power supplies. It looks like the data sheet says that to get POE+ you need 2x1100w or 1x1100w & 1x715w. Do we need to step up to the WS-C3850-48PF-S?

View 1 Replies View RelatedCisco Switches :: ESXi Management Not Working With SG500 LAG
Jan 8, 2013I am setting up a 3 host ESXi cluster. I am using a pair of stacked SG500-28 switches for switching redundancy. Each host has 8 NICs. 4 to each switch. I have successfully setup a 3 NIC LAG with 1 path to one switch and 2 paths to the other. These LAGs work. When I setup a 2NIC LAG via the console for management, and the associated ports on the switches, I lose managment communication with the host. Before setting up the LAG in the ESXi console, I set that vswitch properties to us IPHASH as instructed here bit.ly/VLaTEt I have attempted to follow those instructions as closely as possible. The one thing that I am wondering is whether the SG series supports etherchannel. I can't find any reference. Either way, it works on the other vswitch that is for vMotion. I can vmkping between the hosts over that LAG. But setting up a LAG on the management vSwitch doesn't?

Cisco Switches :: SG500-28P Does Not Handle NLB In Unicast Mode
Apr 8, 2013We have a problem with NLB on a SG500-28P which is a major issue for us.
I am investigating a problem together with Microsoft Support about a download/upload performance issue with a Microsoft Forefront TMG array which is connected to a single SG300-28P. Àpparently this issue exist on every NLB array we implement. I am now at the point we asume the SG500-28P does not handle NLB in unicast mode very well.
We have a network topology as shown below:Please note the actual public IP Addresses are hidden and the internal IP Addresses are diffrent, for security reasons.
Our SG500-28P is configure in L3 mode. It hosts three subnets you see above. The two TMG servers are configured with NLB (in unicast mode) on the Internal Network and External Network interface. It is connected to the internet and our internal network. These TMG Servers are in fact Edge Servers. Our other servers and client are in a different VLAN. The default gateway flows through this NLB Cluster [10.250.0.254].
Problem: When a client uses its default to connect to the internet the performance is very and very slow. With an internet connection of 10/10 we get 10/2. With an internet connection 100/100 we only get 7/1!.
Now we have tried everyting we can imagine. I can't write down all, because that would be a lot. One thing is worth notice; When we move the client to the same VLAN as the NLB Cluster and the client uses 10.250.0.1 as its default gateway, the problem still exists. But... when the client uses 10.250.0.254 as its default gateway the performance is outstanding 95/95! Apparently if traffic for the NLB Cluster is routed through the SG300-28P the performance drops like a rock.
I have never seen this before with SG300 series switches, although this environment is different. Normally I would configure NLB in multicast mode. But the switch does not allow to add static ARP entries for multicast MAC Addresses.I know NLB in unicast mode introduces switch flooding and such. But why does the SG500 not handle this right? Is there anything I can do about it?
Cisco WAN :: SG500-24 - Switches Between Cable Modem And Router?
Feb 25, 2013Currently, my Cisco DPC3010 cable modem is connected directly to one of the Ethernet ports on my Linux router. All works quite well that way. However, I'm curious to know if there's some what to separate the router and cable modem over 2 switches?
The coax enters the house in my living room and connects to the CM there. The router is also sitting in the living room, and it's connected to a Cisco SG200-18 switch. I have Ethernet running from my living room to my basement, where a Cisco SG500-24 switch sits. The two switches are connected via a 2xGigE port channel.
I want to move the router into the basement. Ideally, I'd like to move the CM down there with it, but I don't have the necessary coax run. So for now, that's out. But... can I go from something like this:
--coax----- Cable Modem ---GigE----- Router ---GigE---- SG200-18 ===2xGigE==== SG500-24
To something like this:
--coax----- Cable Modem ---GigE----- SG200-18 ===2xGigE==== SG500-24 ---GigE----- Router
I tried it, complete with a separate VLAN specifically for the CM traffic. And the VLAN was properly trunked between the two switches. But for some reason, the router was unable to communicate via IP to the upstream. I'm not sure if there are config bits I need to set on the SG200 that the CM is connected to? I thought I'd read somewhere that CMs don't like broadcast technology such as LLDP and/or CDP, so I disabled both of those on its port. Did I miss something else perhaps? Or am I trying to do the impossible?
For what it's worth: the IP connectivity is static. There's no DHCP running between my router and the upstream cable provider. The cable modem is literally acting as a L2 coax-->Ethernet convertor, more or less.
Cisco Switches :: SG500 Possibility To Bind ACL To A Virtual Interface
Mar 24, 2013I have a switch from SG 500 Series the works as Layer 3 Routing Switch with the Firmeware 1.2.7.76. I have create some diferent VLAN´s and have defined one ACL for each VLAN. Now i try to do a binding from the ACl to a VLAN but i have only the option to bind the ACL to a phys. Interface or a LAG.is the a possibility to bind the ACL to a virtual interface like in other Cisco serieses and how it works ? the Backround is i have connectetd 2 Hyper-V Server where the Guests are in different VLAN´s and the server is connectetd with a 10Gb Trunk to the Switch now the switch routed the different VLAN´s and i must have some restrictions between the VLAN´s.
View 2 Replies View RelatedCisco Switches :: SG500-28P Slow Switch Uplink Connectivity
Feb 26, 2013At our office we have a weird performance problem with the following switches and connectivity:
Internet |
SG300-24 (L3) core switch (in our server room)
|SG300-10P (L2) access swtich (in our meeting room) |
SG500-28P (L3) switch (in our meeting room)
We are building a new computer infrastructure that is connected to the the SG500-28P. As you can see above the SG500-28P in our meeting room has an uplink to the SG300-10P in the same meeting room. And again the SG300-10P has and uplink to the SG300-24 in our server room. From the server room, there is connectivity to internet. The network uses a multiple VLAN's and routeing between them. Bootom line is, the internet VLAN ID 10 is tagged to trunk ports and available on the SG500-28P. So client get connected straight into the internet based VLAN.
The performance on the SG500-28P switch itself from VLAN to VLAN is very fast. But... the uplink connection tot the internet and other VLAN's on the core switch are very and very slow! At least 10 times slower than normal. So if I plug a laptop in the SG500-28P and go from uplink to uplink, it is slow! But... when I connect the same laptop to the SG300-10P the connection with only one uplink it is fast. As if three switches is to much. I can't figure out why.
Cisco Switches :: From SG500 Port Appears Up But At SG200 It Is Disabled
Jan 4, 2013I have an SG-200-8 which connects to a stacked pair of SG500-28P switches. It is powered by PoE from the SG500. From the SG500 the port appears Up, but at the the SG200 it is disabled and nothing I do re-enables it. I know the cable is good because I had a previous netgear switch hanging off it and working, also the power gets through.I can only connect to the switch if I disable wifi and plugin a manually configured PC - DHCP doesn't get through to it from the SG500 end.I have tried a second SG200 same problem. Have disabled RSTP/ STP thinking it might to relate to the fact that a PC connected to the switch also had a wifi connection to the same LAN, but. Don't know where to go next. looks like a bug?

Once I configure and aplly an IP Interface to a certain VLAN the swtich becomes inaccessable right away. I am pretty sure I am not pulling my own VLAN under my connection. Every port is inaccessable. I have to pull the power plug and restart the swtich with its saved configuration. Even when I add another IP interface to the default VLAN 1, same issue. I have tried lot's of things, but can't get it to work properly. I have just upgraded to the latest firmware.
I have configured dozens of SG300 swtiches which is very easy. This one does not work with me.
Cisco Switches :: SG500 - Migrate From Default VLAN1 To Different VLAN
Mar 1, 2013I have an SG500 that is already deployed with some Access VLANs on it. The PVID is still the default 1. I am trying to change it to 19 with as little interruption as possible. If I just go to the VLAN Management Tab and change the Default VLAN to 19 and reboot the switch, will it migrate my management IP to the default VLAN without any trouble? Would it be less interruption to: Create VLAN 19, assign it an out of subnet IP address, change a port to PVID 19, connect directly to that port, go to that IP address, remove the original management IP from PVID1, change all the ports to PVID19 then change the management IP back to the original?
