Configuration of Stacked Access Switches Solutions

A switch stack is a set of up to nine Catalyst 3750, 3750-E, 3750-X switches connected through their StackWise ports, or up to four 2960-S switches connected through their FlexStack connectors. One of the switches controls the operation of the stack and is called the stack master. The stack master and the other switches in the stack are stack members. The stack members use the Cisco StackWise (or FlexStack) technology to behave and work together as a unified system. Layer 2 and Layer 3 protocols present the entire switch stack as a single entity to the network. The stack master is the single point of stack-wide management.

NOTE: Catalyst 3850 switches cannot be stacked with any other switch model and maximum stack size is 4. As with 3750X switches all members must be running the same feature set.

Adding 3750-X Switches to Existing Stacks of 3750/3750-E Switches

Adding 3750-x switches to existing stacks can cause issues. Please note the following recommendations:-

1. An existing stack needs to be running the minimum level of IOS (minimum IOS version is 12.2(53)SE2 but IOS version 12.2(55)SE and later recommended) to support the 3750-X hardware before any attempt is made to add the 3750-X to the stack.

2. Ensure that the 3750-X switch is running the same IOS release (IOS 12.2(55)SE or later recommended) and has the same licence enabled as the existing stack members before it is added to the stack.

3. If the existing stack is running multiple IOS feature sets (e.g. IP Services on the master and standby and IP Base on the other members of the stack) then the stack will require to be upgraded so that all stack members are running the same feature-set. The 3750-X switch that is being added to the stack will also have to have the same licence to be enabled (IP Services in the example).

4. Due to issues found when carrying out this testing it is not recommended to use the archive command to upgrade all stack members at the same time. The recommendation is to use the archive command with the /destination-system option and upgrade each member of the stack individually.

How to Configuring LLDP & LLDP-MED

LLDP is an open standards based equivalent of CDP.  It is also known also as 802.1AB. If a non Cisco IPT solution is being implemented it may be necessary to configure LLDP-MED. Non Cisco IPT solutions traditionally used DHCP as the mechanism for the phone to discover which voice VLAN is to be used. Cisco IPT solutions use CDP. If the non-Cisco voice solution is designed to use LLDP then LLDP requires to be enabled on the end-user ports. The decision to use LLDP is part of the IPT design. It’s important to confirm with the IPT designer which method (DHCP or LLDP) is being used to assign the voice VLAN information to the IP Phone, to confirm whether LLDP is required. Over time it is expected that more non Cisco solutions will use LLDP as it prevents the need for large DHCP scopes.

For a detailed comparison of LLDP-MED and CDP, see the following link:

http://www.cisco.com/en/US/technologies/tk652/tk701/technologies_white_paper0900aecd804cd46d.html

LLDP removes the need for a non-Cisco IP phone to use DHCP to discover the voice VLAN, using the LLDP-MED network-policy profile type, length & value (TLV) to specify the values for VLAN, class of service (CoS), differentiated services code point (DSCP), and tagging mode. Additionally LLDP-MED can be used to negotiate lower power (e.g. 4W instead of 7W for a Nortel IP phone 2004 with appropriate firmware which supported LLDP-MED (NTDU92)).

Simply configuring the user port for the relevant Nortel/AVAYA IPT (with voice and access VLANS, relevant qos service policy etc), as usual, and then enabling LLDP should be sufficient in most cases to support non-Cisco IP Phones. Please refer to the QoS documentation for details of the LAN QoS configurations for non-Cisco IP Phones.

Protecting the CAM Table using Port Security

On a Cisco Catalyst Switch, are very specific microchips that are used to copy an Ethernet Frame one an ingress port to an Egress port based on SRC and DST MAC Address. Among one of the other functions of the CAM table is to store the MAC Address Table.

In a CAM Table Attack, the attacker attempts to flood the switch with bogus MAC addresses to exhaust the resources of the CAM table thus forcing the switch to forward receive on a given interface out ALL interfaces in the attached VLAN. This in turn gives the attacker the ability to capture and analyze traffic on his computer to gather information destined to computers other than his computer. For example, Server to Server communication or Client to Server communication that is unencrypted could easily be viewed by Wires hark in this type of attack.

Port Security is a layer 2 security features that limits Catalyst switch port(s) to only learn a configured amount of MAC addresses before triggering an administrative action such as disabling the port or restricting the port. When a switchport with port security configured with a maximum of 3 MAC Addresses receives a frame with a NEW SRC MAC address other than the 3 already known ones, it will trigger the administratively configured action. By default this is to shut down the interface and place it into ERR-DISABLED mode.

First off you start out with the simple command switchport port-security. Keep in mind this command can only be executed on an access port so the interface must be set to switchport mode access.

Once port-security is enabled on the interface you can than configure the parameters as needed. To configure the maximum address limit per interface you’ll use the switchport port-security maximum 3 command whereas 3 is the limit.

There are three types of violation actions; shutdown, restrict and protect. The default action of a port-security violation is to shut down the interface into ERR-Disabled mode. The restrict and protect actions perform the same function but the primary difference is that the security violation counter is incremented with restrict whereas it’s not with protect. Both Restrict and Protect will drop all frames from a SRC MAC address that violate port-security configuration.
