Cisco Switching/Routing :: Maximum Number Of Licenses For Connections To A 877?
Jan 11, 2012Is there a maximum number of licenses for connections to a 877?The reason I ask is that our routers are managed by a datacentre and when I asked for the login details I was told that I couldnt have them due to licensing reasons with no other explanation.

Oct 21, 2012I'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.

Oct 30, 2012I am trying to configure a SNORT IDS system running on a physical machine using Linux as the base OS. I have a small lab network setup with 3 VLANs, a 3548 switch and a 2611 router acting as the router on a stick/inter-vlan router. My goal is to setup SNORT as a host-based IDS system. To do that I know I need to use the "port monitor" command on the switch and I have tested this and it works fine only when the snort system and the traffic I want to monitor reside on the same VLAN.My problem is I want to be able to monitor a trunk link betwee the switch and router to see traffic coming from my 3 VLANs which contain servers. My goal is to run attacks on the servers to test SNORT's effectiveness.
Relevant information from my configuration: interface fa 0/1 on switch is the trunk like carry 3 vlans to the router On the switch:
int fa 0/1
switchport mode trunk
int fa 0/5
port monitor fa 0/1
switchport mode access
The switch will not allow me to configure fa 0/5 as a trunk, only can be an access port.So right now, SNORT does not see any traffic other than traffic from my router to the switch. I assume because this is going over the native VLAN (1 in this case) and that is the same VLAN that SNORT box resides on on interface fa 0/5. So I know the span is working to an extent, but traffic from my other VLANs (server to server traffic) does not show on SNORT at all.I have done some research on Cisco.com and see the following seemingly contradicting information:
VLAN Filtering When you monitor a trunk port as a source port, all VLANs active on the trunk are monitored by default. You can use VLAN filtering in order to limit SPAN traffic monitoring on trunk source ports to specific VLANs Then I see, under the section for the 3500 series: A monitor port cannot be a dynamic-access port or a trunk port. However, a static-access port can monitor a VLAN on a trunk, a multi-VLAN, or a dynamic-access port. The VLAN that is monitored is the one that is associated with the static-access port.
My question is, does that mean the 3548 cannot support spanning a trunk link and having all VLANs on that trunk be monitored correctly to the monitoring port? I know the 3548 is old, but it is the only thing right now I have to work with. I could put the SNORT box inline on the network, but that is another mess in itself.

View 4 Replies View RelatedLinksys Wireless Router :: EA4500 Maximum Number Of Port Forwards
Apr 19, 2012Background: currently have a WRT320N, thinking of upgrading to an EA4500 assuming ONE feature has been improved: Port Forwarding.
Scenario: Currently I have a WRT320N router, and while it "does everything we need" it has one limitation that is now getting in the way: limitation on number of forwardable ports. In the port forwarding panel, it has 15 total rows: the first five rows can be enabled for specificaly named services (SMTP, FTP, etc). The last 10 rows are fully customizable in that we can set the name, ports and protocol.
The problem is that of the 13 total ports I currently need to forward, only ONE of them is listed in that fixed list. So, sadly, I can only use one of those first five rows. I've now filled the remaining ten custom rows, and still have need for two additional ports (for now, may need more down the road).
Trying to get creative, I figured maybe I could just spill over to the Port Range Forwarding page and add a row or two there. The only problem: it's buggy. I've found that if the Single Port Forwarding list is filled, then the Port Forwarding Range entries don't work properly. For example, if I wanted ports 12345 and 12346 forwarded to 192.168.1.5, they work fine with two single port forwarding entries. However, if I delete those, add two other port lines I need forwarded (the single list being full again), and add a port forwarding range 12345..12346, they don't work properly, ports just are closed. Only the singles work, the ranges don't.
Question: Has the EA4500 resolved this issue and allow for either more lines (i.e. 20 customizable entries instead of 10), or, better, does it just have an [Add Entry] button to allow for additional rows to be created? In today's day and age, where one single device (such as an Xbox) can take four rows, a 10-row limit is pretty sparse. Comparing it to some competitors, for example the D-Link DIR-825 (aging, but still great) allows you to add as many as you want.
I realize "expensive" firewalls like SonicWall's have virtually unlimited customization, but I don't need many of the additional features and don't want to spend $350 on a "high-end" firewall to solve the problem of needing two more ports open.
Cisco Switching/Routing :: MAC Without Port Number Cat6500
Oct 30, 2012We have IP device on the farm switch(cat6500, which is an access layer siwtch), with the gateway on the core switches (Nexus7000), on the core when I do show ip arp, I found the mac.But when I do sh mac add add of that mac there is no port attached to that mac.
Since that particular vlan only resides on the cat 6500 and two cores, so I logged in to the 6500, and when I show mac- in that vlan, I didn’t find that mac addresss. Instead, I found another mac address with last 8bit are the same of that mac.
Is it some kind VIP of the mac? How so, if no port, how can the switch forward the frame? [code]

Cisco Switching/Routing :: Cannot Find Port Number From MAC Address Using SNMP With 3725
Dec 2, 2012I'm developing a project where I use the SNMP protocol to discover the network. By discovering the network I mean go through all the routers and switches and retrieve the IP routing table from routers and the forwarding table from switches. With the routers I have no problem. For the switches I need to know for each port the MAC addresses and the Vlans. Basically it's use SNMP to find a port number from a MAC address. To do that i followed this tutorial: [URL]
The problem is that I'm using a Cisco 3725 Router with IOS 12.4 (21) and a NM-16ESW module to work as a Switch and when I use the OID .1.3.6.1.2.1.17 corresponding to the BRIDGE-MIB as it follows:
snmpwalk -v2c -c myrouter 10.1.1.5 .1.3.6.1.2.1.17
it returns:
SNMPv2-SMI::mib-2.17.1.1.0 = Hex-STRING: 00 00 00 00 00 00
SNMPv2-SMI::mib-2.17.1.2.0 = INTEGER: 0
SNMPv2-SMI::mib-2.17.1.3.0 = INTEGER: 4
From this I guess there's no information on the router about Vlans or anything. Other thing is that when I use community string indexing it returns a timeout. My theory is that this version doesn't support indexing but I don't know.
how can I get the Port Number from a MAC address from this "switch" (it's a router working as a switch) using SNMP?
Cisco Switching/Routing :: Change Number Of Internal Port-channel On Nexus 5000
Jan 3, 2012I'm in the middle of a Nexus 5000 project and recognized today while configuring port-channels, that some of the interface numbers are reserved for internal use.
Is it possible to change or configure which port-channel interface numbers are allocated for internal use by NX-OS?
Unfortunatly I wasn't able to find a solution for this issue in the offical Nexus documentation, the search function of this forum or Google. If I did miss something or didn't look careful enough at the Nexus docs, I'm also happy with RTFM (... fine manual) responses and links to the info :-)

Cisco Application :: Ace 20 Total Number Of Concurrent Sessions Sudden Drop
Jul 18, 2012I´m detecting on my ACE 20.
I´m monitoring the total number of concurrent sessions of my ACE 20 (using Cacti), and from time to time, with no discernable pattern, I see an instant drop of sessions to half...I don´t detect any disturbance with our traffic and service, I have no complaints, but it's a very accentuated drop.
I´m able to get 1 or 2 days withouth any suddent drop of connections, and then for no reason I pass from 500.000 to 200.000 sessions in a minute. Then they gradually go up again.
I´ve seen in ACE´s session table that she keeps a great number of half-open, or closed sessions, and those are counted as part of concurrent sessions. Is there any flush on ACE´s table when she reaches a certain number of closed TCP sessions or something like that?

The power supplies have eventually made a popping noise and had to be replaced. on the 4510s we've tried two chassis and gone through several power supplies.The switches have been behind UPS systems so should be receiving conditioned power.Could load from the PoE devices really be causing this? I wouldn't think it's power since they are behind a UPS.

Cisco Switching/Routing :: Policing Traffic On 4510?
Nov 21, 2012I have two servers on one subnet that each need to replicate to a single server on another subnet. They also need to replicate to each other. This replication is unidirectional so I will refer to the 2 server subnet as the source subnet and the single server subnet as the destination subnet. In order to keep this replication running without killing the MPLS links on either end, we are trying to use a policy-map that limits bandwidth from the source subnet.The Problem:We have created a policy that polices traffic during specific times of day and limits the bandwidth as prescribed, however, bandwidth is also being limited between the 2 servers on the source subnet which is not needed or desired.Class 512K set dscp ef police 1024000 bps 1024000 byte conform-action transmit exceed-action dropClass Map match-any 512K (id 4) Match access-group name DAGExtended IP access list DAG 10 permit ip host 10.20.0.3 host 10.20.0.10 time-range DAG-REP (active) (22793 matches) 20 permit ip host 10.20.0.4 host 10.20.0.10 time-range DAG-REP (active) (14156 matches)The service policy is applied on the input side of the 2 interfaces on which our devices are connected.As you can see, the access list identifies the interesting traffic as traffic from two specific hosts to one specific host. The problem we are having is that bandwidth is also being throttled between the two source hosts even though it is not defined to do so.What can I do to limit traffic from the two source devices to the single destination device without limiting bandwidth between the two source devices?

Cisco Switching/Routing :: Speed Up Connection Between 6509 And 4510
Feb 21, 2013I got a 6509 version 12.1(22)E2 that I am replacing with a 4510E version 3.40SG with Supervisor Engine 7-E. The 6509 is configured with 20 channel-group for dual fiver connection to ten 3550 switches with trunking enabled with isl encapsulation. The 6509 is the VTP server to each of the 3550 switch clients. There are 40 Microsoft Servers attached ot the Gig RJ45 port modules.
I have attached the 4510 to the 6509 with dual fiber connection configured as a channel group with trunking enabled. I am configuring the 4510 the same as the 6509 except I have to use trunking with dot1q encapsulation because isl is not supported on the 4510. I no longer want to use VTP with the 4510 and have set the it as transparent mode. Each of the 3550 switches are changed from isl trunking encapsulation to dot1q and VTP mode is changed to transparent when they are moved from the 6509 to the 4510.
I want to move the switches over a few at a time and not all at once. The first 4 switches attached with no problems and ran with no problems for the user access to the servers still on the 6509 for a week. Then I found out DHCP was not working for the devices attached to the switches on the 4510. I moved one of our domain controllers form the 6509 to the 4510 to fix the DHVP problem. I have now added 2 more switches with users that use an application on a server still on the 6509 and they are getting disconnect errors after logging into it and using it. Other applications on different server also on the 6509 are having no problems. I moved the switches back to the 6509 to get the users up during business hours. I now plan on moving the server for the application that was failing to the 4510 in hopes that it will fix the problem.
Is there something I can do to speed up the connection between the 6509 and the 4510 so I can continue this transition without having to move the servers to the 4510 as I move the users?
