Cisco WAN :: How To Remove Subnetted Route On Catalyst 3560
Nov 15, 2011
I have been researching a way to remove this subnetted route from my L3.There is an extra subnetted route that should not be there when I execute the command: show ip route
Below if part of my Show Run and the Show IP Route commands. You will see the 10.0.0.0/24 subnet as subnetted. I dont know why the L3 uses the 10.0.0.0/24 when I enter 10.10.10.0/24? But thats a whole different questions.
interface Vlan1
no ip address
shutdown
!
interface Vlan2
ip address 10.10.10.1 255.255.255.0
!
interface Vlan3
I have a really weird issue with my cisco catalyst 3560G.
-device: cisco catalyst 3560g -ios: 12.2-53(SE) IP SERVICES
scenario: configured IPv6 iBGP link between this switch and a router. the router is announcing 1 (test) route. the switch sees the route properly, but doesn't add it to routing table (the route never gets to be "best path", although it should be).
A check out a network segment and want to know why SwA has a static route to SwB if SwA already has a Default GW to Core?
(SwA, SwB - Catalyst3560, Core - Catalyst4948)Note, there are distribute list on SwA - it does not has any OSPF route (exclude O*IA).
Does this mean when SwA send out packet with DA 10.5.64.0/26, Core will use only L2 switching (instead of L3)? Is this more effectively for Core Switch?
Pleace check my reasoning: 1. When use a static route: SwA receive packet from Vlan 20 with DA 10.5.64.0/26 it will strip out Dest. MAC and replace it with MAC of SwB. Core will switch this packet to SwB based on mac add. table (l2 switching)
2. When SwA has only Default gateway and receive packet from Vlan20 with DA 10.5.64.0/26 it replace Dest. MAC with Core MAC. Core receive this packet, lookup route table for 10.5.64.0 entry and forward packet base on this.
I'm part way through trying to set a Catalyst 4510R to factory defaults, One thing I'm stumped on is how do i remove the Customer Disclaimer eg what commands do i need to remove this and any other customer text within the switch, below is copy of text from the switch with customers details omitted.
how to safely remove the WiSM2 from the Catalyst 6500 series switch? According to the documentation "Catalyst 6500 Series Wireless Services Module 2 Installation and Verification Note":
To remove the WiSM2, perform these steps:
Step1 Shut down the module by one of these methods: In privileged mode from the router prompt, enter the hw-mod module mod shutdown command. NoteIf you enter this command to shut down the module, you must enter the following commands in global configuration mode to restart (power down, and then power up) the module: Router# no power enable module modRouter# power enable module mod If the module does not respond to any commands, press the SHUTDOWN button located on the front panel of the module.
Step2 Verify that the WiSM2 shuts down. Do not remove the module from the switch until the POWER LEDis off.
But, in the case of Step1 (1st methods) I do not see a option "shutdown" in the command "hw-mod module 3"...
All I prompted to enter is: c6500#hw-module module 3 ?
boot Specify boot options for the module through Power Management Bus control register
reset Reset specified component
simulate Simulate options for the module Is it hidden options?
IOS version of c6500 is 12.2(33)SXJ1
In the case of Step2 (2nd methods) there is not any button on the front panel of the module?
And yet, it is better to remove the module configuration manually or use the command module clear-config prior to removing the module?
I'm having trouble with a Cisco Catalyst 2950 Series Switch where by I'm following the procedure from Cisco's web site to remove the Banner and login information, url..
Each command is being accepted by the switch from following the information given within the help sheet above,the problem i have now is when i turn the power off then turn the switch back on I'm still getting the banner and login information even though i have follwed Cisco's help correctly.
The traffic flow on the network is fine, but we are not able to access our remote locations.Using the example in that thread:Let's use your example. If your Vlan interfaces are configured on the 3560:
interface Vlan10 description LAN A ip address 10.20.102.1 255.255.255.0 interface Vlan 104 description LAN B ip address 10.20.104.1 255.255.255.0
Device A has his default gateway set to 10.20.102.1 (interface Vlan10) and device B has his default gateway configured to 10.20.104.1 (interface Vlan104). If device A (10.20.102.55) wants to talk to device B (10.20.104.25), the traffic would have been routed on the 3560 between Vlans 102 and 104.
As for DHCP, if there is a server on a separate network (let's give the DHCP server an ip: 192.168.2.15) you would configure an 'ip helper-address' on each vlan, which will forward each DHCP Discover broadcast to the DHCP server as a unicast packet. This is done because by default the router (3560) will not forward broadcasts.
interface Vlan10 description LAN A ip address 10.20.102.1 255.255.255.0 ip helper-address 192.168.2.15 interface Vlan 104 description LAN B ip address 10.20.104.1 255.255.255.0 ip helper-address 192.168.2.15
Now lets say LAN A and LAN B are located in SITE1. A second site, SITE2, has the address of 10.20.128.1. I can't ping the Site2 location from the LAN B (10.20.104.x) segment in Site1. I think I should set a static route on our switch with something like this:
ip route 10.20.0.0 255.255.0.0 10.20.102.10
The address 10.20.102.10 would be a wan router in this example.
I want to upgrade a Catalyst 3560-48PS to the last IOS.I get an errormessage stating that there is insufficient space in flash: I have deleted all files in flash - but I still get the same error message. According to the documentation there should be enough memory. Messages are pasted below:

We have a IP-phone system connected to port 1 on a 3560 switch, the phone system tags traffic with dscp. The switch uplink is on port 24. Is this configuration correct:
I have purchased two catalyst 3560 switches (with 24 interfaces) on Ebay to prepare for ccnp switch exam. It would be great if I have 4 switches. Is it any possibillity to create two logical switches from one? I mean, not by assigning interfaces to different vlans?
I have been getting notifications of large packet loss and latency for itnernal traffic going to servers. I have a simple setup of nagios who pings servers and will notify me of large packet loss or complete packet loss. I have implemented this L3 switch a few hours ago, I am currently running a constant ping to my servers, but I am not niticing packet loss right now.This packet loss happened 4 time spans within the last hour of many large packet losses to all my servers within all subnets. It is now stopped.
I am not sure why this would be happening, the predessor of the internal router was just a normal linux box with 3 NICs on it. Nothing crazy going on since the business is closed.
we have applied route-map on vlan interface in the form:
ip access-list extended TEST permit ip 172.16.1.128 0.0.0.127 172.16.0.0 0.0.255.255 route-map TEST permit 10 match ip address TEST set ip next-hop 172.16.111.1 interface Vlan11 ip policy route-map TEST
The problem is in the traffic matching by the rule - there is matches not only for 172.16.0.0/16 prefixes but for the whole traffic in that VLAN.
I'm a C# programmer and as part of my software I need to monitor some Cisco Catalyst 3560V2 24 switches using SNMP (By reading MIB/S data).Apparently this switch supports more than 50 different MIBs.My question is which MIB/MIBS contains general health data (parameters) that may determine if the switch is OK, Degraded or Malfunctioned.
I'm currently configuring per port policing on a 3560 and want to limit inbound traffic to 750mbit:
mls qos access-list 1 permit any class SET_IF match access-group 1 policy-map SET_QOS class SET_IF

When I test the setup with iperf I always get different results when I change the nummber of parallel connections.Isn't there a way to limit the throughput regardless of the number of conns (INGRESS!) like with srr-queue bandwith limit?
We have observed increase of CPU utilization of 50% after upgrade from 15.0(1)SE3 to 15.0(2).The SDM template is "desktop default" template.The increase of CPU utilization in Switches with LAN Base after upgrade is about 10%.
How to find the cause for the 50% increase ?This is command is the output of 15.0(2). The calculated sum for 5min process-utilization is 21% plus 1% interrupt is 22 %. Where is the rest ?

My first question is I have an access layer switch which is a single VLAN and I am trunking that VLAN to a distribution layer switch, I can ping the gateway on the distribution layer switch for THAT VLAN, But cannot ping the gateway address for the second VLAN I have on the distribution layer switch. I know it is simple, But I have forgotten and just need a push
Also I have a third VLAN set to route traffic not bound for those 2 VLANs out to a router is the statement "ip route 0.0.0.0 0.0.0.0 172.16.252.2" good enough and do I actually need to create a VLAN for that traffic? and if so, is an access switchport the best option?
Im trying to Connect a 2960-S Catalyst Switch to a 3560 Catalyst Switch. It worth pointing out im newish to switching although i know some commands and what they do This is my first time connecting 2 switches together.They are connected via a crossover cable and have green lights flashing on the connected ports When i run "show CDP neighbours it sees the new switch Unable to ping new switch...just timesout Here is the the interface on the 3650
GigabitEthernet0/40 is up, line protocol is up (connected) Hardware is Gigabit Ethernet, address is 001b.532f.8428 (bia 001b.532f.8428) Description: Uplink to Switch 2 MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, reliability 255/255, txload 1/255, rxload 1/255
I know its probably got something to do with EIGRP no auto-summary, I was wondering if I could get some input as to why a route would change from being variably subnetted, which is usually the case until no auto-summary is deployed. Or am I totally lost? I attached a screen shot for a closer observation.
I m connected to a LAN With about 1500-2000 other clients. My network has been subnetted into several small networks according to the hostels (i study in a university). Most effective way to implement INTER-hostel file sharing.Each hostel has typically about 200 clients.
I am trying to implement static route tracking on a Catalyst 3560G ( WS-C3560G-48PS, IOS version 12.2(35)SE5 and SW image C3560-IPBASE-M). The configuration is as follows:
track 101 rtr 1 reachability ! rtr 1 type echo protocol ipIcmpEcho 10.199.101.2 rtr schedule 1 life forever start-time now ! IP address 10.199.101.2 is reachable via ICMP (its the next-hop router).
The static routes configured are the following:
ip route 0.0.0.0 0.0.0.0 10.199.101.2 track 101 ip route 0.0.0.0 0.0.0.0 10.200.52.1 20
But only the secondary route(ip route 0.0.0.0 0.0.0.0 10.200.52.1 20) its being installed on the routing table by the switch.
The 3560 switch is serving as an access and distribution layer switch. End devices are connected to it and it also implements IP routing via SVI and L3 ports.Auto qos voice cisco-phone has been implemented on applicable access layer ports. SRND4 is being used.
Question 1:Why is the auto qos generated policed-dscp map different on these two switches?The Cisco Smart Business Architecture LAN configuration files guide [URL] does not specifically use the 3560 in their examples, they use the 3750 but it's my assumption that the same techniques, configs apply with regard to my specific feature questions. When using a 3750 in the Access layer, the guide shows (page 15) the same auto qos generated policed-dscp map configuration that is on my 2960. The SBA LAN config guide shows that when using a 3750 as a Distribution layer switch (page 26), the policed-dscp map configuration is the same that I see on my 3560.In the configuration guide for the 3750 distro switch, there is no auto qos applied as there are no access ports, so the mls qos commands are manually input. Since my 3560 does have access ports, auto qos generated the mls qos commands, and the results are the same be it following the guide and manually entering (per distro switch guidelines) or using auto qos. This leads to question 2...
Question 2:Why is the mls qos map policed-dscp configuration different depending on use as an access vs. distribution switch?
Question 3: On the 3560, access ports that have "auto qos voice cisco-phone" applied are put into queue-set 2 (output). Queue-set 2 (output) uses default values (not configured). Is this correct and desirable? If so, why? The 2960 has all ports in queue-set 1, regardless of being an access device port or a trunk port connected to the 3560 (as per the SBA LAN config guide EgressQOS macro commands). The 3560 trunk ports are all also configured to use queue-set 1 (output), again as per the SBA LAN config guide EgressQOS marco commands.
I have one specific trouble with Catalyst 3560CG switch and Stardom reserved industrial controller. Controller has 2 processors, one of them after(!) negotiation become main with IP 192.168.1.1, other one stays in reserve with IP 192.168.1.129. If main one shuts down, spare one becomes main with IP 192.168.1.1. This perfectly works with DLINK and MOXA level 2 switches, but fails with Catalyst 3560, because spare one cannot even connect to switch port. I don't know the exact reason of it, but i suspect, that it happens because of before negotiation both controllers have ip 192.168.1.1 (i know, that it is wrong and weird, but so it goes). First of them correctly connects to switch port, which goes up and passes pings. Second processor tries to connect to switch port, which goes several times up and very soon down, then processor lefts his tries to connect to anybody and become idle. The switch seems to some way check IPs of 1-st and 2-nd port packets, and shuts down 2-nd port. I have connected via hyperterminal and tried to disable some level 3 functions and checks of the switch, but this wasn't useful. how exactly(or at least approximately) should i configure a switch to make this bundle work?
I have two Catalyst 3560 series switches with a 100Mb Ethernet microwave link and a 250Mb Ethernet microwave link between them. Can the switches be set up to make full use of the added bandwidth (350 Mb).
I've just installed 2 of these in my workplace on a PLC network.I'm now looking to set one of the ports up as my diagnostic port and would like to be able to mirror any of the other ports to this port.I believe it is called SPAN on Cisco switches.The only reference I can find to it is configuring via Telnet which I haven't got a clue about.On my old Wiedmuller switches it was just a few clicks away.
