E120 and E320 System Maximums

The following tables provide system maximums for the E120 and E320 routers.

General System Maximums

Table 8 lists some general system maximums for the E120 and E320 routers. The following notes are referred to in Table 8:

  1. The maximum number applies to any combination of VRs and VRFs. The number of VRs and VRFs that you can configure depends on your configuration. You cannot achieve the maximum number if each VR and VRF instance is running a routing protocol.
  2. The maximum of 3000 VRs and VRFs can be achieved only with the SRP-120 and SRP-320 modules, which have 4 GB of memory. The limits cannot be achieved with the SRP-100 module, which has 2 GB of memory.

Physical and Logical Density Maximums

Table 9 lists physical and logical density maximums for the E120 and E320 routers. The following notes are referred to in Table 9:

  1. Wire rate indicates the port density that supports maximum (wire-rate) performance. Oversubscribed indicates the port density possible if you are willing to accept less than wire-rate performance by oversubscribing the available fabric bandwidth.
  2. With a 120-Gbps configuration on the E120 router, you can install up to six combinations of ES2 10G Uplink LMs, ES2 10G LMs, or ES2 10G ADV LMs in slots numbered 0-5. You can install a maximum of six active ports and six redundant ports at any time.
  3. With a 100-Gbps fabric configuration on the E320 router, you must install the ES2 10G Uplink LM or the ES2 10G LM in either of the E320 router turbo slots (2 and 4). When the ES2 10G Uplink LM or the ES2 10G LM is installed in slot 2 or slot 4, you cannot install another line module in slot 3 or slot 5. In this case, you can install the ES2 4G LM only in slots 0–1 and 6–11; therefore, the maximum number of ports and the forwarding performance per chassis is reduced for the IOAs that pair with the ES2 4G LM.

    With a 320-Gbps fabric configuration on the E320 router, you can install up to 12 combinations of ES2 10G Uplink LMs, ES2 10G LMs, or ES2 10G ADV LMs in slots numbered 0-5 and 11-16. You can install a maximum of 12 active ports and 12 redundant ports at any time.

Link Layer Maximums

Table 10 lists link layer maximums for the E120 and E320 routers. The following notes are referred to in Table 10:

  1. On the ES2 10G LM, ES2 10G ADV LM, or ES2 10 G Uplink LM, you can have configurations with up to 100,000 static entries that support 100,000 DHCP relay proxy clients. You can have an additional 28,000 static or dynamic entries for network resources, such as RADIUS and DHCP servers. However, the total number of dynamic entries in the ARP table is still restricted to a maximum of 32,768 per line module.
  2. On the E120 router, the SRP-120 and the SRP-320 support a maximum of 64,000 interfaces.
  3. On the E320 router, the SRP-320 supports a maximum of 96,000 interfaces. The SRP-100 supports a maximum of 64,000 interfaces.

  4. The E120 router supports a maximum of 64,000 interface columns of all types combined. The E320 router supports a maximum of 96,000 interface columns of all types combined. You can use all dynamic interfaces, or all static interfaces, or a combination of dynamic and static interfaces to achieve this maximum.
  5. The JunosE Software supports up to 10,000 PPP interfaces with EAP authentication negotiation configured. Performance and scalability is unchanged when EAP is not configured.

  6. The E120 router supports a maximum of 64,000 Ethernet subinterfaces that can be active at any one time. The E320 router supports a maximum of 96,000 Ethernet subinterfaces that can be active at any one time. Of this total, you can configure all single-tagged VLAN subinterfaces, all double-tagged S-VLAN subinterfaces, or a combination of both VLAN subinterfaces and S-VLAN subinterfaces to achieve this maximum.
  7. The E120 router and the E320 router support 16,384 VLAN subinterfaces per slot on the ES2 4G LM and the ES2 10G LM, and 32,768 VLAN subinterfaces per slot on the ES2 10G ADV LM. On the E120 router, a maximum of 64,000 VLAN subinterfaces is supported per chassis. On the E320 router, a maximum of 96,000 VLAN subinterfaces is supported per chassis. You can use all dynamic interfaces, or all static interfaces, or a combination of dynamic and static interfaces to achieve this maximum.
  8. For all LMs, no more than 16,384 S-VLANs are supported per port. The ES2 10G ADV LM supports 32,768 S-VLANs per module. All other LMs support only 16,384 S-VLANs per module.
  9. For all LMs, no more than 4096 VLANs are supported per port. The ES2 10G ADV LM supports 32,768 VLANs per module. All other LMs support only 16,384 VLANs per module.
  10. No more than 8192 VLAN major interfaces are supported per line module.

Routing Protocol Maximums

Table 11 lists routing protocol maximums for the E120 and E320 routers. The following notes are referred to in Table 11:

  1. The total set of FTEs can be shared by interfaces, next hops, ECMP sets, VRs, and VRFs. Next-hop FTEs identify the next hop on multiaccess media, such as ATM multipoint, Ethernet, or bridged Ethernet. Each VR or VRF consumes three entries. Each interface, next hop, and ECMP set consumes a single entry. One FTE is reserved for internal use, and the system software limits the number of FTEs used by interfaces to a maximum of 32,000. The remaining FTEs can be shared across the other types.
  2. You can use either all dynamic interfaces or a combination of dynamic and static interfaces to achieve this maximum.
  3. Even though 128,001 IP interfaces are supported, only a maximum of 96,000 subscribers are supported per chassis. A combination of single-stack and dual-stack subscribers to use all 128,001 interfaces is not supported.
  4. These values are subject to limitations on available SRP module memory, which varies according to your router configuration.
  5. Depending on your configuration, the router may support more routing table entries or fewer routing table entries than this value. In any case, you can choose to limit the number of routes that can be added to the routing table on a per-VR or per-VRF basis by means of the maximum routes command.
  6. The maximum number of ANCP adjacencies can be scaled over a maximum of 100 virtual routers. Fewer ANCP adjacencies can be scaled in configurations with more than 100 virtual routers.
  7. On the E320 router, you can achieve 32,767 total Martini circuits only over Ethernet interfaces. For all routers, the total Martini circuits can be any combination of external inter-router circuits and internal circuits (local cross-connects).
  8. There is no per-VR limit; all multicast routes can be on a single VR or present across multiple VRs.
  9. The maximum number of interfaces can be achieved by any combination; for example, two streams each being replicated to 32,768 interfaces; 16,384 streams each being replicated four times; or any other combination.

Policy and QoS Maximums

Table 12 lists policy and QoS maximums for the E120 and E320 routers. The following notes are referred to in Table 12:

  1. For more information about system resource requirements for nodes, queues, and shadow nodes, see JunosE Quality of Service Configuration Guide, Chapter 15, QoS Profile Overview. QoS is supported on all E Series line modules except for the ES2 10G Uplink LM.
  2. For all line modules the maximum number of IPv4 or IPv6 or VLAN policy attachments is determined by the maximum number of interfaces multiplied by the number of attachment resources that are currently used. Attachment resources are used only when you attach the policy.
  3. The line modules support policy attachments based on the following considerations:

    • IPv4—Up to 2 ingress policy attachments and 1 egress policy attachment
    • IPv6—Up to 2 ingress policy attachments and 1 egress policy attachment
    • IPv4 secure policy—The ES2 4G LM, the ES2 10G LM, and the ES2 10G ADV LM support up to 1 ingress policy attachment and 1 egress policy attachment
    • IPv6 secure policy—The ES2 4G LM supports up to 1 ingress policy attachment and 1 egress policy attachment
    • VLANs—Up to 1 ingress policy attachment and 1 egress policy attachment
  4. Secure policies are not supported on the ES2 10G Uplink LM. IPv6 secure policies are not supported on the ES2 10G LM.
  5. For each rule that is sent from the SRC server using COPS messages to the SRC client, which is a router running JunosE Software, an entry is created in the policy table of the SRC client. A portion of the memory on the SRC client is needed to hold these policy rule entries that are transmitted to the SRC client for enforcing the policy decisions that are sent from the SRC server. The maximum number of memory blocks that is allocated to the SRC client functioning on the router for the policy rules that are sent from the SRC server is 1,024,000.
  6. The number of QoS profiles or policies that you can attach depends on the number of IP (IPv4 and IPv6) interfaces that you have created. However, the maximum number of QoS profiles or policy interface attachments per chassis is limited to 128,000.
  7. You can configure compound shared shapers only on a line module with the TFA hardware. You can determine the support for compound shared shapers on the line module by executing the show qos shared-shaper command.

Tunneling Maximums

Table 13 lists tunneling maximums for the E120 router and the E320 router. The following notes are referred to in Table 13:

  1. The ES2-S1 Service IOA supports any combination of DVMRP, GRE, and L2TP tunnels up to a maximum of 8000 tunnels; however, no more than 4000 tunnels can be DVMRP or GRE tunnels in any combination.
  2. For more information about supported L2TP sessions and tunnels, see JunosE Broadband Access Configuration Guide, Chapter 12, L2TP Overview.

Subscriber Management Maximums

Table 14 lists subscriber management maximums for the E120 router and the E320 router. The following notes are referred to in Table 14:

  1. DHCP relay proxy maintains a list of active DHCP clients up to a maximum of 100,000 clients per chassis for all virtual routers. DHCP relay does not maintain a list of DHCP clients.
  2. DHCP relay proxy is notified of DHCP client deletions and subsequently deletes the client's host routes. In contrast, DHCP relay is not notified of DHCP client deletions, so the host routes for deleted clients remain in DHCP relay until you permanently delete them with the set dhcp relay discard-access-routes command. A maximum of 100,000 host routes for DHCP clients can be stored for all DHCP relay and DHCP relay proxy instances (that is, for all virtual routers).

  3. On the E120 router, the SRP-120 and the SRP-320 support a maximum of 64,000 interfaces.
  4. On the E320 router, the SRP-320 supports a maximum of 96,000 interfaces. The SRP-100 supports a maximum of 64,000 interfaces.

  5. For DHCPv6 local server, up to 32,000 subscribers and clients are supported on PPP/ATM and PPPoE/ATM with dynamic interfaces. Interface flapping tests have been qualified for 8000 subscribers and interfaces.

    Informational Note: The system maximum and line card maximum values mentioned in the tables are for single dimension scaling only. We recommend that you test scenarios that require scaling of multiple features to the maximum values concurrently, before deploying.
    For example, on E320 routers, we support 96,000 PPP subscribers and 1, 500, 000 BGP 4 routes (NLRI). These values are independent of each other. We recommend that you test that the system can concurrently support 96,000 PPP subscribers and 1,500,000 BGP 4 routes (NLRI), before deploying.
