Cisco Switching/Routing :: 3750 / 2950 - Which Series Switch Supports Vlan Up To 4000
Nov 4, 2012we are using 3750 and 2950 switches both of them do not support vlan up to 4000 .we need vlan about 3000 .Whic cisco series switch do support vlan up to 4000.
2950
S-SW1.3(config-vlan)#exi
Proposed configuration has too many VLANs for this platform. Reduce the number of VLANs proposed.
S-SW1.3(config)#end
3750
SW1(config-vlan)#exi
proposed configuration exceeds the limit of 1005 VLANs that can be supported on this platform. Reduce the number of VLANs proposed to be within this limit.
Cisco Switching/Routing :: Does 3750 / 3560 Switch Support Eigrp Or Ospf
Feb 17, 2013I believe the answer is yes, but incorperating more layer 3 features of our 3750's, I want to know if they fully support EIGRP or OSPF?
Also for a small business of 4 locations, each with a 10mbps fiber and a 1.5mbps mpls... wouldn't you say EIGRP would be easier? Want to look at making the failover automatic if the 10mbps fiber goes down between a site, then the network fails over to 1.5mbps mpls. When the fiber returns in service then the network automatically preferr the fiber again.
Currently we use static routes and if there is a provider outage we have to manually edit the config to flip flop the routes.

Jul 10, 2012Any switch that supports 4096 multicast groups?I am working on a system that includes over a dozen catalyst 2960 switches. The customer has pointed out the 2960 switch does not satisfy the requirement to support 4096 multicast groups (even though it is more than adequate for the number of active multicast groups). It looks like the 3560 supports more multicast groups than the 2960, but is still far less than the requirement.

View 4 Replies View RelatedCisco Switching/Routing :: 3560 / 3750 - Enterprise LAN Environment / Could Not SSH
Feb 1, 2012I am working in an enterprise LAN environment. We have about 100 switches, mostly 3560 and 3750's. This is a typical Cisco network, yet it's flat. No routing on the access layers. The core switch does do the routing. We use an third party vendor network monitoring tool, and we use Secure CRT to remote into devices.
Here's the problem. There was a device we stumbled into that had not been put into our monitoring software. It has the same IOS as our other devices. All I can say is that it's the same version and type. Each device has a management v LAN. And each device has it's own management IP. An ACL exists to prevent unauthorized SSH access into the devices, yet allows the management v LAN scope to get in.
So, here's the problem...we can't SSH into our problem mystery device, let's call it Switch X. Switch X has an IP of 10.10.100.150. Now, I can be logged into it's up link device, let's call it switch B. Switch B has an IP of 10.10.100.130. The ACL allows all devices from 10.10.100.0/24 to SSH. Our PC's at our desk are also in the same management V LAN. SSH version 2 is on the configs, and the domain names are the same on these two devices.
So, let's be clear. From my desktop, I can connect to any device on my network EXCEPT switch X. When I try to connect using SSH, port 22...it just sits there until it times out. I can do the same thing to any other switch, and connect just fine. We are using TACACS+ and RADIUS as well, and they are up and running just fine. The configs on Switch X like I said are the same for switch B, except it's IP address of course. While logged into switch B, I can do a CDP neighbor and see switch X connected via trunk link. Both sides are running dot1q encapsulation, and both are in trunk mode. I can ping switch X from switch B. When I try to SSH from B to X..I get timeout with no connection.
So, I hiked over to the building where switch X is located. I consoled into the switch. I confirmed that the ACL is the same as the ACL for switch B. It is set up to allow the management v lan inbound on the VTY 0 - 15. Yes, it's access-class (name) in on both vty 0 4 and 5 15. It also is set up for transport ssh in and transport ssh out.
I rechecked the domain name on Switch X; it was correct. I also did a crypto key and regenerated the crypto key. SSH v2 came up. Again, while in Switch X, I can do a CDP neighbor and see switch B. But I cannot SSH from switch X to Switch B, or any other devices that I tried. Now, we did find a config error with VTP; the VTP domain name was different. But VTP has nothing to do with SSH. Just to placate my co-workers, I went ahead and renamed the VTP domain name (it's running transparent mode). After I regenerated the crypto key, I saved everything of course. I then reloaded the switch. When all came back up, I still could not SSH
This is a 3560 switch, and it is trunk to a 3750.
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

View 4 Replies View RelatedCisco Switching/Routing :: 3560 And 3750 - Any Way To Check For MLS QoS Input Queue Drops?
Feb 10, 2012I feel that 3560 and 3750 perform differently with the following two commands:
srr-queue bandwidth shape 5 0 0 0
srr-queue bandwidth limit 50
On 3750, the bandwidth for queue 1 is limited to 100mbps x 50% / 5 = 10mbps
On 3560, the bandwidth for queue 1 is limited to the smaller value of BW / shape weight and BW x limit%.
Does it sound about right? is there a way to check for mls qos input queue drops? The show mls qos interface xxx stat only shows the output queue drops. Maybe for some reason the input queue never drops?
Cisco Switching/Routing :: 3750 / 3560 / 7945s - Verifying Maximum Support

once it leaves the switch and enters into Edge router and if we do not have configured QoS in router which is normally MQC , how does it process each packet ?Do we need to have end to end QoS configured in LAN ?
Cisco Switching/Routing :: Cat 3560 No Switchport Command Test Out Routing With Switch
Dec 8, 2011The last few days I've been exploring options in getting rid of some old routers accross a wan connections. I have a cat 3560 to play with and I thought I would try and use the no switchport command test out routing with switch. I've got some type of route issue and I tried a few things which I thought would fix the issue but had no effect. I'll post the config and a few commands so you can see what the basic setup is.
Here we can see in the arp that it knows about both 10.7.1.2 (PC unable to ping 10.3.3.254) as well as 10.3.3.254 (ASA).I tried adding in a ip route of 10.7.0.0 255.255.0.0 10.3.3.110 as well as 10.3.3.254. Neither produced the results I wanted allowing 10.7.1.2 (PC) to ping the ASA (10.3.3.254). [code]
Cisco Switching/Routing :: 3560 VLAN Routing Between Switch And Router
May 8, 2012I have an environment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. Remaining 2 Cisco 3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . On all three switches I have created multiple VLANs and assigned ports to these VLAN. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Now the issue is how I am going to have all these VLANs routed through single interface on the routeri-e f0/0, as all these subnets will communicating to remote site over VPN. What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches.
I have read inter-VLAN routing i-e creating sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN?

Cisco Switching/Routing :: QOS Config On 3560 Switch
Jul 22, 2012I'm in the process of configuring QOS on a 3560 routing switch in a GOLD, SILVER, BRONZE priority type scenario.
Firstly, I understand that this config will add a tag of "precedence 5" to a packet if it matches the "ACL_QOS_GOLD_In" access list. Question is does the router see this "precedence 5" tag and then sets the priority, or am I missing something in my config where at present it just sees the "precedence 5" and doesn’t act on it ?
Secondly, Since the "precedence 5" tag has already been added to the packets, do downstream routers see this tag and act accordingly or so I need to configure those is well ? [code]
Cisco Switching/Routing :: Configure QoS On 3560 Switch?
Jun 7, 2012configure QoS on 3560 switch i have taken the template from cisco configuration guide since we have different QoS configuration on each model.
below is the configuration :
configure terminal
mls qos
end
mls qos map cos-dscp 0 8 16 26 32 46 48 56
no mls qos srr-queue input cos-map mls qos srr-queue input cos-map queue 1 threshold 2 1 mls qos srr-queue input cos-map queue 1 threshold 3 0
[code]....
Currently all the cisco phones are connected to this switch and configuration with only one vlan that is voice vlan .
1) what is the outcome of this configuration , i mean, what will be the expected output ? end of the day we need to prioritize the voice traffic but why other commands including threshold and buffers are mentioned with respectives queues , if I need to explain that what am i expecting out of this configuration ?
2) this is LAN QoS which i understood but again , do i need to configure policy-map along with class-map which is MQC on this switch ?
3) i have edge router where i have MQC already configured but confusion with this switch which is working as a Access switch .
4) I referred the cisco QoS document for the respetive model whereas we have policy-map configured on the same switch with class-map .
My understanding is if we have configured the LAN QoS , and mapped the CoS value with DSCP , we need not to have MQC.
Cisco Switching/Routing :: 3560 - IOS On Switch Model?
Nov 9, 2011I am configuring some quotes for a customer whom I will be building a wireless network for. The wireless network will support about 60 AP's, as well as some other wired drops. The customer is working with a wireless vendor for the AP's, but I will be able to sell the switches for the network.
I want to ensure that he is pushing Gig and POE on each copper port for the AP's, since they will be "N" capable. I have selected several 3560 models which are in 24 port models, and I also think i have a requirement which mandates a 48 port in another location. What I have not been able to find in the Enterprise switch line is an 8 port which supports IOS and POE.
That being said, and since I am also "Select" certified, I went out to the SMB site, and did find that there were two models in the Small Business 300 line (models SG300-10P and SG300-10MP) which seem to support Gig ports as well as POE. I looked over the specs for each one of the two respective models, and I was not able to find what the difference between each of these two are. In other words, the specs, line by line, were identical.

View 3 Replies View RelatedCisco Switching/Routing :: Output Queue Drops On 3750 Core Stack And 3560 Edge Switches
Jan 10, 2013I've been fighting what seems to be an increased number of outqueue drops on our core stack and edge switches for the last 3 or 4 weeks.(The core consists of a stack of 5 3750s in 32-gig stack mode. The wkgrp switches are 3560s. all are at 12.2.52) The wkgrp switches are directly connected to users. We use Nortel IP phones with the phone inline with the user PC. auto-neg to 100/full. [code] However I have tried turning off QOS on a couple of workgroup switches (no mls qos, but left individual port configurations the same) but am still seeing drops.Since I have disabled qos on the switches in question (no mls qos) (not the core tho) I am presuming these commands have no affect on the switch operation and therefore cannot be related to the problem. With QOS turned off one would presume that it is general congestion - especially at the user edge where busy PC issues might contribute. So I wanted to see if I could see any instances of packets in the output queues building up.
I wrote some scripts and macros that essentially did a snapshot of 'show int' every 20 seconds or so, and looked for instances of 'Queue: x/' where x was greater than zero.What I found after several days of watching the core stack, and a few of the workgroup switches that are most often displaying the behavior, was that I NEVER saw ANY packets in output queues. I often saw packets in Input queues for VLAN1, once in a great while I would see packets on input queues for fa or Gi interfaces, but NEVER on output queues. [ code] Additionally, when I look (via snmp) at interface utilization on interfaces showing queue drops (both core and wkgroup), they are occurring at ridiculously low utilization levels (as low as 4 to 8%). I've tried to look for microbursts between the core and a wkgroup switch where the core interface was experiencing drops, but haven't seen any (using observer suite). [code] While the queue-drop counts aren't critically high at this point, they are happening more frequently than in the past and I would like to understand what is going on... In most cases, no error counters are incrementing for these interfaces. Is there some mechanism besides congestion that could cause output queue drops?
