Cisco Switching/Routing :: Cat 3560 No Switchport Command Test Out Routing With Switch
Dec 8, 2011
The 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]

I created new VDCs. Since I have done so, there is not switchport command under the interface configuration.
The interesting this is that it is available on the admin VDC, but not the new VDC I created. I cannot create a peer VPC Peer link between my 2 Nexus switches. I did allocate ports to the new VDC and I did verify the enabled feature are the same.
why the switchport command is not available?

We have two catalyst 3560 switches running c3560-ipbasek9-mz.122-58.SE2.bin They are connected using etherchannel using gi 0/21 - 24 interfaces.
on 3560-1 switch, there isn't any ip-default gateway or ip route configured. It only have 1 interface vlan configured.
on 3560-2 switch, there is ip default gateway configured along with 1 interface vlan.
What i dont understand here is that, i can reach out to other subnets from 3560-1 switch in which the routing is not enabled?

I 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?

I am trying to get my workstation to talk to a workstation on a different sub-net through a Cisco 3560 switch. The switch is running the following IOS version: [code]
My primary network is 172.16.0.0 and I am trying to connect to a device on a 192.168.111.0 sub-net. [code]
What would be the best way to get the two workstations talking via the switch?

Any way to test in a lab what would happen if a tech mistakingly added "switchport voice vlan XX" to a trunk port? I am try to do some RCA on an issue and this has been identified as a possible cause by one of my techs.
The config is Switch1------Switch2--------Switch3 Each interswitch connection is configured as a dot1q trunk with all vlans allowed. The link between switch2 and 3 is where switchport voice vlan 10 was added. Switch1 is a 3750 and 2/3 are 3560's.

show cdp neighbors command shows two devices connected through the same local port?I have a Cisco 3560 that when I issue the "show cdp neighbors" command I get the following results: [code]
the question is why is this showing that Gig0/3 is being used twice to connect to two different devices. I have verified there is no hub connected to this port and in fact Switch3 is not connected to Switch1 at all yet it still shows up in the CDP table.
I have cleared the CDP table on every device at this location and still get the same results.

I have issue with 3560 switch QoS configuration . I checked in cisco site about mentioned model QoS configuration.once we mark the frame and map the CoS to DSCP and once it enters into switch and it processes according to LAN QoS configured on interface
we have configured both the commands shape and share.
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 ?

I have a 3560-48 switch running Cisco IOS Software, C3560 Software (C3560-ADVIPSERVICESK9-M), Version 12.2(44)SE3 and i need to implement basic QOS commands to the fast Ethernet interfaces as well as the gig interfaces and Also I need to create port channels on the switch and need what the port channel syntax are as well for that particular IOS version?
I have only read only access and i can't see what the QOS and Port channels syntax should be for that IOS version.

I'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]

configure 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.

I 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.

I need to enable vPC "peer-switch" command on a pair of Nexus 7018s which are currently vPC peers (primary and secondary). The STP root and Secondary root are currently configured across these switches.Can I enable the peer-switch command in this configuration without impacting services, and then modify both switches to have the same bridge priority without impacting services ? We have a few downstream 5ks which are not dual homed to both vPC peers (work in progress) so need to understand if the peer-switch command will in any way break this connectivity for now.

I have a 3560 switch with 1 VLAN (VLAN 10) where I need to make ports:
1-10 as isolated (can't contact each other)
11-20 as community (need to contact each other like a normal VLAN)
23 as promiscuous (server that ports 1-20 need to get to)
24 as promiscuous (WAN router where ports 1-20 need to get to and the remote servers).

I have an issue with a 3560 in my network, after sometimes it fails to give out power to some ip phones,while others are not affected and below is the message i get
"Power given, but Power Controller does not report Power Good"
output of sh power inline and sh env all : everything seems to be ok on the switch
#sh power inline
Available:450.0(w) Used:48.0(w) Remaining:402.0(w)

Gi0/1 auto off 0.0 n/a n/a 15.4
Gi0/2 auto off 0.0 n/a n/a 15.4
Gi0/3 auto off 0.0 n/a n/a 15.4
[code].....
It's solved by a reboot of the switch, i could have suspected a power environnment issue but it's the only equipement disturbing in the network.

I am trying to configure 802.1x wired on a 3560 switch and don't see the required commands under the interface. I am running c3560-ipbasek9-mz.122-55.SE6.bin. I was thinking it might not be available on the ipbase image, but I do have the commands on a 3750g running the ipbase image, so I'm not sure about that.

I have made a topology by using one 3560 switch and 2 2950 switches. I have also made 2 vlans name Clients and other Servers and vlan 1 is for anagement purposes. The left 2950 switch is for clients and the right is for servers. Clients is vlan 2 and servers is vlan3 . Now what i want is that my dhcp is should assign ips to clients in vlans 2 provided that servers are in vlan 3. I am also using a border router and i have introduced a default route on the 3560 to the border router.
Now when i assign static ips to my clients pc and server dhcp then i can ping between vlans but when i try to assign ip through dhcp then it wont work. Also the default route on the switch to the border router doesnt seem to work. I can ping only the border router when i put a default route on the border router instead of the 3560 switch.
