Voice VLAN Configuration

•Before you enable voice VLAN, we recommend that you enable QoS on the switch by entering the mls qos global configuration command and configure the port trust state to trust by entering the mls qos trust cos interface configuration command.

• The Port Fast feature is automatically enabled when voice VLAN is configured. When you disable voice VLAN, the Port Fast feature is not automatically disabled.

• When you enable port security on an interface that is also configured with a voice VLAN, you must set the maximum allowed secure addresses on the port to at least two.

• If any type of port security is enabled on the access VLAN, dynamic port security is automatically enabled on the voice VLAN.

• You cannot configure static secure or sticky secure MAC addresses on a voice VLAN.
Configuring a Port to Connect to a Cisco 7960 IP Phone

VOICE VLAN CONFIGURATION:

Because a Cisco 7960 IP Phone also supports a connection to a PC or other device, a port connecting the switch to a Cisco 7960 IP Phone can carry mixed traffic.

You can configure the port to carry voice traffic in one of these ways:

• Configuring Ports to Carry Voice Traffic in 802.1Q Frames

• Configuring Ports to Carry Voice Traffic in 802.1P Priority-Tagged Frames
You can configure the IP phone to carry data traffic in one of these ways:

• Overriding the CoS Priority of Incoming Data Frames

• Configuring the IP Phone to Trust the CoS Priority of Incoming Data Frames
switchport voice vlan dot1p :

Instruct the switch port to use IEEE 802.1p priority tagging for voice traffic and to use the default native VLAN (VLAN 0) to carry all traffic. By default, the Cisco IP phone forwards the voice traffic with an IEEE 802.1p priority of 5.
switchport voice vlan vlan-id

Instruct the Cisco IP Phone to forward all voice traffic through the specified VLAN. By default, the Cisco IP Phone forwards the voice traffic with an 802.1Q priority of 5. Valid VLAN IDs are from 1 to 4094.
switchport priority extend cos value :

Set the IP phone access port to override the priority received from the PC or the attached device.
The CoS value is a number from 0 to 7. Seven is the highest priority. The default is 0.

switchport priority extend trust
Set the IP phone access port to trust the priority received from the PC or the attached device.

Installation of Cisco Expansion module 7916

Installation of Cisco Expansion module 7916

When you add an expansion module new Cisco IP phone, the module acts weird. Sometimes there is no label displayed.
First reset the phone by unplugging the Ethernet cable and plug back in. Press # during the power up time. Press 123456789*0# when the button lights are moving one to another. Wait until the phone downgraded to factory default. Then the phone will be upgraded to latest firmware from the call manager. Once the phone is upgraded to latest firmware, the firmware will be displayed under active ID in call manager under device properties. Then plug the module, add the module name under device, module section and save the config. Then apply the config. The expansion module will start to work.

Missed calls log missing

It happens to some Cisco IP phones that missed calls log become empty. It is a weird situation and it may confuse the end users. You may see this behavior in ccm 7.x version. The problem won't go away even if you reset the firmware to default version and then upgrade to the latest version. The best solution is to remove the phone device and directory number from the data base. make a search that directory number does not exist in call manager. Then create the phone and assign the directory number to the phone.

Juniper SRS FW Redundancy

you must connect the fe-0/0/7 port to the fe-2/0/7 port to form the control link. For

SRX240 devices, connect the ge-0/0/1 port to the ge-5/0/1 port to form the control

link. For SRX650 devices, connect the ge-0/0/1 port to the ge-9/0/1 port to form the

control link. For a device from the SRX3000 line, the connection that serves as the

control link must be between the built-in control ports on each device. SRX5000 line

devices do not have built-in ports, so the control link for these gateways must be the

control ports on their Services Processing Cards (SPCs) with a slot numbering offset

of 6 for SRX5600 devices and 12 for SRX5800 devices.

FABRIC PORT CONNECTION

The fabric link connection for the SRX210 must be a pair of either Fast Ethernet or

Gigabit Ethernet interfaces and must be any pair of either Gigabit Ethernet or

10-Gigabit Ethernet interfaces on all other SRX Series devices. Figure 170 on page

912, Figure 171 on page 912, Figure 172 on page 912, Figure 173 on page 913 and Figure

174 on page 913 show pairs of SRX Series devices with the fabric links and control

links connected

Juniper NSM HA Setup

In HA deployment:
Copy the above 2 files to the primary and secondary server as shown above and ensure that files ownership are nsm.

Then instead of restarting GuiSvr & DevSvr service, perform the following:
Stop the HaSvr process of the stand-by server:
NSMStandby # /etc/init.d/haSvr stop
Restart the HaSvr process of the active server:
NSMActive # /etc/init.d/haSvr restart
Once the services on the primary server are all up and running, start the HaSvr on the stand-by server:
NSMStandby # /etc/init.d/haSvr sta

IDP Database update

Upon the installation of your NSM...before you can add you IDP appliance, you must update the attack database...this would mean.. your nsm server will query the juniper website where the idp attack database resides...

one of the requirements on updating the attack database is that your nsm server must have direct access to the internet...with proper dns configured.

Once this is addressed, just click on the NSM Tools > View/Update NSM Attack Database.

Juniper IDP

The unit can operate in either passive mode, or inline mode. Passive mode is just for sniffing the network, and it can block certain types of attacks by landing an RST packet within the TCP window. However, it cannot block non-TCP attacks, only log them. And it is possible that the blocking that is available in passive mode can happen too late, the malicious payload has already been sent by the time the blocking happens.

In inline mode, you have 3 options for installing it. You can use Layer-3, where the IDP gets an IP on each interface and you actually set up routes to it. In Bridge mode it will participate in spanning tree, and transparent mode, it just passes everything unmodified including spanning tree packets.

If you plan on putting the unit inline, Transparent mode is the preferred method. Especially if you have 2 units and are putting them in parallel between two switches as spanning tree will continue to operate as if the units were not even there.

When running in inline mode, you can group interfaces into Virtual Routers. These don't necessarily route, unless you're operating in layer-3 mode. But, the do tell the unit which interfaces are grouped together so you can pass traffic for particular network segments, and VR's will NOT pass traffic between each other. So if I had 8 interfaces, I could create 4 VR's with 2 interfaces each, and effectively put the unit inline on 4 totally separate network segments. Inline mode is the way to go if the unit will handle the throughput.

Set the unit up through the web interface on the unit to configure the modes you want to run in and any Virtual routers. Then install the NSM on your management console and add the device. When creating your policy, it's good practice to only put it in logging mode for at least a couple of weeks to see what kind of alerts you are getting and make sure you don't block legitimate traffic. Then go through and put in any exceptions you need and eventually put it into blocking mode.

Mobility - One number to reach

Intercom a type of phone line, combines the functionality of a traditional line and a speed dial. With an intercom line, a user can call the intercom line of another user, which auto-answers to one-way audio whisper. The recipient can then acknowledge the whispered call and initiate a two-way intercom call. Users can use an intercom line to dial any other intercom line in the intercom partition, or you can preconfigure the line to target an intercom line outside the intercom partition.
The following are the steps to create
1. Create intercom partition- Intercom partition is already created in Call Manager.

2. Intercom calling Search Space: Intercom CSS already in Call manager, we are using INTERCOM 10 for the configuration.

3. Create INTERCOM Translation Pattern:
Go to Call Routing > Intercom > Intercom Translation Pattern, Add New

Please add the directory number of the user who uses Intercom. The details of the fields are
Intercom Translation Pattern Enter the intercom translation pattern, including numbers and wildcards (do not use spaces), in the Intercom Translation Pattern field. For example, for the NANP, enter 9.@ for typical local access or 8XXX for a typical private network numbering plan. Valid characters include the uppercase characters A, B, C, and D and \+, which represents the international escape character +. If you leave this field blank, you must select a partition from the Partition drop-down list box.
Note Ensure that the intercom translation pattern, which uses the chosen intercom partition, route filter, and numbering plan combination, is unique.
Check the route pattern/hunt pilot, translation pattern, directory number, call park number, call pickup number, or meet-me number if you receive a message that indicates duplicate entries. Alternatively, check the route plan report if you receive a message that indicates duplicate entries.
